Rajab Month in Islam: What Is Authentic and What Is Weak
Contents
Every year, as the Rajab month begins, phones fill up with messages: a special Rajab dua, a reward for fasting its first day, a prayer for its first Friday night, a celebration on the 27th. Some of these come from authentic hadith, and many do not. This article sets out what the Prophet ﷺ actually said about Rajab, and labels the popular narrations that are weak or fabricated, with the scholars who graded them.
At a glance
- What Rajab is: The 7th Islamic month and one of the four sacred months
- Authentic hadith here: 7, from Bukhari, Muslim, Abu Dawud and an-Nasa’i
- Weak or fabricated: The Rajab dua, “Rajab is the month of Allah”, Salat al-Ragha’ib, special Rajab fasts
- Rajab 1448: Expected to begin around 11 December 2026 (the moon sighting decides)
- One thing to do: Guard yourself from wrongdoing in the sacred month, and start preparing for Ramadan
1. Rajab is one of the four sacred months
Abu Bakrah (may Allah be pleased with him) heard the Prophet ﷺ name the sacred months during his sermon at the Farewell Hajj:
إِنَّ الزَّمَانَ قَدِ اسْتَدَارَ كَهَيْئَتِهِ يَوْمَ خَلَقَ اللَّهُ السَّمَوَاتِ وَالأَرْضَ، السَّنَةُ اثْنَا عَشَرَ شَهْرًا مِنْهَا، أَرْبَعَةٌ حُرُمٌ، ثَلاَثٌ مُتَوَالِيَاتٌ، ذُو الْقَعْدَةِ وَذُو الْحِجَّةِ وَالْمُحَرَّمُ وَرَجَبُ مُضَرَ الَّذِي بَيْنَ جُمَادَى وَشَعْبَانَ
Time has returned to the state it was in on the day Allah created the heavens and the earth. The year is twelve months, four of which are sacred: three in a row, Dhul-Qa‘dah, Dhul-Hijjah and al-Muharram, and Rajab of Mudar, which comes between Jumada and Sha‘ban.
Sahih al-Bukhari 4662 · Narrated by Abu Bakrah · Translation adapted from Sunnah.com
Rajab stands on its own, apart from the other three. It is called “Rajab of Mudar” because the tribe of Mudar was known for honouring it. HadeethEnc explains that fighting was forbidden in these months, and that the Arabs before Islam had shifted the sacred months to suit their wars; this sermon returned them to their original order (HadeethEnc 10104). The Quran gives the same count and adds a clear instruction:
إِنَّ عِدَّةَ ٱلشُّهُورِ عِندَ ٱللَّهِ ٱثْنَا عَشَرَ شَهْرًا فِى كِتَـٰبِ ٱللَّهِ يَوْمَ خَلَقَ ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضَ مِنْهَآ أَرْبَعَةٌ حُرُمٌ ۚ ذَٰلِكَ ٱلدِّينُ ٱلْقَيِّمُ ۚ فَلَا تَظْلِمُوا۟ فِيهِنَّ أَنفُسَكُمْ ۚ وَقَـٰتِلُوا۟ ٱلْمُشْرِكِينَ كَآفَّةً كَمَا يُقَـٰتِلُونَكُمْ كَآفَّةً ۚ وَٱعْلَمُوٓا۟ أَنَّ ٱللَّهَ مَعَ ٱلْمُتَّقِينَ
Indeed, the number of months with Allāh is twelve [lunar] months in the register of Allāh [from] the day He created the heavens and the earth; of these, four are sacred. That is the correct religion [i.e., way], so do not wrong yourselves during them. And fight against the disbelievers collectively as they fight against you collectively. And know that Allāh is with the righteous [who fear Him].
Surah At-Tawbah 9:36 · Translation: Saheeh International, from Quran.com
Try this: treat Rajab as a month to be more careful: hold your tongue, settle a dispute, and stay away from what you already know is wrong, since “do not wrong yourselves during them” is the one command the verse gives about these months.
2. Fasting in Rajab: what the Prophet ﷺ did
When a student of Ibn ‘Abbas was asked about fasting in Rajab, during Rajab itself, he did not quote a special Rajab virtue. He described the Prophet’s ﷺ normal pattern of voluntary fasting:
سَأَلْتُ سَعِيدَ بْنَ جُبَيْرٍ عَنْ صَوْمِ، رَجَبٍ – وَنَحْنُ يَوْمَئِذٍ فِي رَجَبٍ – فَقَالَ سَمِعْتُ ابْنَ عَبَّاسٍ – رضى الله عنهما – يَقُولُ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَصُومُ حَتَّى نَقُولَ لاَ يُفْطِرُ. وَيُفْطِرُ حَتَّى نَقُولَ لاَ يَصُومُ
I asked Sa‘id ibn Jubayr about fasting in Rajab, and we were in Rajab at the time. He said: I heard Ibn ‘Abbas (may Allah be pleased with them both) say: “The Messenger of Allah ﷺ used to fast until we would say he would not stop fasting, and he would leave fasting until we would say he would not fast.”
Sahih Muslim 1157c · Narrated by ‘Uthman ibn Hakim al-Ansari, from Sa‘id ibn Jubayr, from Ibn ‘Abbas · Translation adapted from Sunnah.com
‘Aishah (may Allah be pleased with her) describes the same pattern, and names the one month he fasted most outside Ramadan:
كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَصُومُ حَتَّى نَقُولَ لاَ يُفْطِرُ، وَيُفْطِرُ حَتَّى نَقُولَ لاَ يَصُومُ. فَمَا رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم اسْتَكْمَلَ صِيَامَ شَهْرٍ إِلاَّ رَمَضَانَ، وَمَا رَأَيْتُهُ أَكْثَرَ صِيَامًا مِنْهُ فِي شَعْبَانَ
The Messenger of Allah ﷺ used to fast until we would say he would never stop fasting, and he would leave fasting until we would say he would never fast. I never saw the Messenger of Allah ﷺ fast a complete month except Ramadan, and I never saw him fast more in any month than in Sha‘ban.
Sahih al-Bukhari 1969 · Narrated by ‘Aishah · Translation adapted from Sunnah.com
So fasting in Rajab is like fasting in any other month: voluntary fasting is good at any time, and no authentic hadith gives Rajab a fast of its own. IslamQA quotes the scholars on this point: “There is no sahih hadith that speaks of the virtues of the month of Rajab” (IslamQA 202017). For the fasts that do have authentic virtues, see the fast of Prophet Dawud and fasting three days each month.
Try this: if you already fast Mondays and Thursdays or three days a month, keep doing it in Rajab, with no new intention tied to the month.
3. No special ‘Umrah in Rajab
Some people believed the Prophet ﷺ made ‘Umrah in Rajab. ‘Urwah ibn az-Zubayr asked ‘Aishah about it:
قَالَتْ مَا اعْتَمَرَ رَسُولُ اللَّهِ صلى الله عليه وسلم فِي رَجَبٍ
She said: “The Messenger of Allah ﷺ did not perform ‘Umrah in Rajab.”
Sahih al-Bukhari 1777 · Narrated by ‘Urwah ibn az-Zubayr, from ‘Aishah · Translation adapted from Sunnah.com
‘Umrah is good in any month. The point is only that Rajab has no ‘Umrah of its own in the Sunnah.
Try this: before sharing a “Sunnah of Rajab” message, ask one question: which hadith, and who graded it?
4. The Rajab sacrifice of the time of ignorance
Before Islam, Arabs slaughtered an animal called the ‘Atirah in Rajab. Abu Hurairah (may Allah be pleased with him) reported:
لاَ فَرَعَ وَلاَ عَتِيرَةَ
There is no Fara‘ and no ‘Atirah.
Sahih al-Bukhari 5473 · Narrated by Abu Hurairah · Translation adapted from Sunnah.com
The same hadith explains that the Fara‘ was the first offspring of the herd, which the pagans slaughtered for their idols, and the ‘Atirah was slaughtered in Rajab. When the companions asked about it, the Prophet ﷺ did not tie sacrifice to Rajab at all:
نَادَى رَجُلٌ رَسُولَ اللَّهِ صلى الله عليه وسلم إِنَّا كُنَّا نَعْتِرُ عَتِيرَةً فِي الْجَاهِلِيَّةِ فِي رَجَبٍ فَمَا تَأْمُرُنَا قَالَ اذْبَحُوا لِلَّهِ فِي أَىِّ شَهْرٍ كَانَ وَبَرُّوا اللَّهَ عَزَّ وَجَلَّ وَأَطْعِمُوا
A man called out to the Messenger of Allah ﷺ: “We used to slaughter an ‘Atirah in Rajab in the time of ignorance, so what do you command us?” He said: “Slaughter for Allah in whatever month it may be, be dutiful to Allah, the Mighty and Majestic, and feed people.”
Sunan Abi Dawud 2830 · Sahih (al-Albani) · Narrated by Nubayshah · Translation adapted from Sunnah.com
An-Nasa’i reports the same answer (Sunan an-Nasa’i 4229, Sahih, Darussalam).
Try this: if you want to slaughter and feed people, do it for Allah in any month, rather than waiting for Rajab.
5. Rajab points ahead to Sha‘ban and Ramadan
Usamah ibn Zayd (may Allah be pleased with him) noticed how much the Prophet ﷺ fasted in Sha‘ban and asked why:
قُلْتُ يَا رَسُولَ اللَّهِ لَمْ أَرَكَ تَصُومُ شَهْرًا مِنَ الشُّهُورِ مَا تَصُومُ مِنْ شَعْبَانَ. قَالَ ذَلِكَ شَهْرٌ يَغْفُلُ النَّاسُ عَنْهُ بَيْنَ رَجَبٍ وَرَمَضَانَ وَهُوَ شَهْرٌ تُرْفَعُ فِيهِ الأَعْمَالُ إِلَى رَبِّ الْعَالَمِينَ فَأُحِبُّ أَنْ يُرْفَعَ عَمَلِي وَأَنَا صَائِمٌ
I said: “O Messenger of Allah, I do not see you fasting in any month as much as you fast in Sha‘ban.” He said: “That is a month people neglect, between Rajab and Ramadan. It is a month in which deeds are raised to the Lord of the worlds, and I love that my deeds are raised while I am fasting.”
Sunan an-Nasa’i 2357 · Hasan (Darussalam) · Narrated by Usamah ibn Zayd · Translation adapted from Sunnah.com
Here Rajab is mentioned as a landmark, the month before the one people overlook. That gives Rajab a practical use: it is two months before Ramadan, which is enough time to build a habit.
Try this: pick one deed now, such as a daily page of Quran, two rak‘ahs at night or a few voluntary fasts, so it is already a habit when Sha‘ban and Ramadan arrive.
Weak and fabricated Rajab narrations
The narrations below are widely shared. They are listed here only to say that they are not authentic, so they have no Arabic cards.
The Rajab dua: “Allahumma barik lana fi Rajab wa Sha‘ban”
The dua “O Allah, bless us in Rajab and Sha‘ban, and let us reach Ramadan” is graded weak. IslamQA explains that its chain includes Za’idah ibn Abi ar-Ruqad and Ziyad an-Numayri, both weak narrators, and names an-Nawawi, Ibn Rajab and al-Albani among the scholars who did not accept it (IslamQA 202017). The same answer says there is nothing wrong with asking Allah, in your own words, to let you reach Ramadan, as long as it is not presented as a Sunnah of Rajab.
“Rajab is the month of Allah”
The saying “Rajab is the month of Allah, Sha‘ban is my month and Ramadan is the month of my Ummah” is “declared unreliable by the Hadith masters”, according to HadithAnswers, which cites Ibn al-Qayyim and adh-Dhahabi among others (HadithAnswers).
Salat al-Ragha’ib on the first Friday night of Rajab
Salat al-Ragha’ib is a twelve-rak‘ah prayer between Maghrib and ‘Isha on the first Friday night of Rajab. IslamQA quotes Ibn al-Jawzi, an-Nawawi, Ibn Taymiyah and Ibn Hajar al-Haytami, who all called the narration behind it fabricated (IslamQA 60180). An authentic hadith also tells us not to single out Friday night for prayer (Sahih Muslim 1144b; see the five don’ts for Friday).
Narrations for and against fasting Rajab
Weak narrations cut both ways. The report that “the Prophet ﷺ forbade fasting Rajab” is graded Da‘if (Darussalam) (Sunan Ibn Majah 1743), and a longer report telling a man to fast from the sacred months is graded Da‘if (al-Albani) (Sunan Abi Dawud 2428). Neither forbids nor commands a Rajab fast, which leaves us with the authentic pattern in section 2.
Is 27 Rajab the night of Isra and Mi‘raj?
The Night Journey and Ascension (al-Isra’ wal-Mi‘raj) is certain, but its date is not. HadithAnswers notes that Ibn Hajar listed more than ten opinions on it, that 27 Rajab is one of them, and concludes: “It is impossible to state conclusively that Mi‘raj occurred on any particular date” (HadithAnswers, The date of Mi‘raj). No authentic hadith attaches a special prayer or fast to the 27th. How to treat that night is a question for a qualified scholar where you live; for the general principle, see the hadith on bid‘ah.
Bringing it together
Rajab is honoured in the Quran and the authentic Sunnah, but the honour is simple: it is a sacred month, and believers are told not to wrong themselves in it. The extra details that travel around each year, the special dua, the first-Friday prayer, the fast with a set reward, are where the weak narrations sit.
Reflection: the most useful thing to do in Rajab may be the least dramatic: fewer sins, the voluntary deeds we already know are authentic, and a plan for Ramadan. Holding to what is authentic is itself a way of honouring the month.
Questions people ask
When is Rajab?
Rajab is the seventh month of the Islamic calendar, between Jumada al-Akhirah and Sha‘ban (Sahih al-Bukhari 4662). Rajab 1448 is expected to begin around 11 December 2026, but the moon sighting decides the exact day.
Is there an authentic Rajab dua?
No. The dua “Allahumma barik lana fi Rajab wa Sha‘ban wa ballighna Ramadan” has a weak chain (IslamQA 202017). Asking Allah in your own words to let you reach Ramadan is fine, without presenting it as a Sunnah of Rajab.
Is fasting in Rajab sunnah?
No authentic hadith gives Rajab a special fast. Voluntary fasting is good in any month, and the Prophet ﷺ followed his usual pattern (Sahih Muslim 1157c). He fasted most outside Ramadan in Sha‘ban (Sahih al-Bukhari 1969).
What are the four sacred months?
Dhul-Qa‘dah, Dhul-Hijjah, al-Muharram and Rajab (Sahih al-Bukhari 4662; Quran 9:36).
Is 27 Rajab the night of Isra and Mi‘raj?
27 Rajab is one opinion among more than ten; scholars say the date cannot be fixed with certainty, and no authentic hadith attaches special worship to it.
