Rajab: The Seventh Islamic Month

Rajab (Arabic: رجب) is the seventh month of the Islamic lunar calendar and one of the four sacred months (al-ashhur al-hurum) in which fighting was traditionally forbidden. The word Rajab is derived from a root meaning "to revere" or "to stand in awe," reflecting the elevated status of this month. The four sacred months are Dhul Qa'dah, Dhul Hijjah, Muharram, and Rajab — three consecutive months and one isolated month.

Status as a Sacred Month

Allah says: "Indeed, the number of months with Allah is twelve... Of these, four are sacred. That is the correct religion, so do not wrong yourselves during them" (9:36). The prohibition of wrongdoing "during them" indicates that sins in the sacred months are more grave than sins in other months, while righteous deeds are similarly amplified. Rajab's isolation — standing apart from the three consecutive sacred months — made it particularly notable to the pre-Islamic Arabs, who observed its sanctity scrupulously. Islam affirmed this sanctity without the innovations the Arabs had added.

The Prophet ﷺ used to supplicate when Rajab began: "Allahumma barik lana fi Rajab wa Sha'ban wa ballighna Ramadan" — "O Allah, bless us in Rajab and Sha'ban, and allow us to reach Ramadan" (narrated by Ahmad, though its chain has been discussed by hadith scholars). This supplication, whether authenticated or not, reflects the traditional understanding that Rajab begins a three-month spiritual runway leading to the blessed month of Ramadan.

The Night Journey: Isra wal-Miraj

According to many scholars, the miraculous Night Journey of the Prophet ﷺ — the Isra (night journey from Mecca to Jerusalem) and Miraj (ascent through the heavens) — occurred on the 27th of Rajab, approximately one year before the Hijra. During this journey, the Prophet ﷺ led all the prophets in prayer at al-Masjid al-Aqsa, ascended through the seven heavens, was shown the signs of Allah, and received the obligation of the five daily prayers directly from Allah. This is among the greatest miracles granted to the Prophet ﷺ. While the exact date is disputed among scholars (some place it in Rabi al-Awwal or Shawwal), the 27th of Rajab is the most widely cited date and is commemorated in many Muslim communities through reflection on this extraordinary event.

Innovations to Avoid

While Rajab is a sacred month, several practices specifically associated with it have no basis in the Sunnah and should be avoided. These include:

• Designating the night of the 27th of Rajab for special prayers (Salat al-Raghaib) — explicitly declared a fabricated hadith by scholars including Ibn al-Salah, al-Nawawi, and Ibn Taymiyyah.
• Fasting the entire month of Rajab as an obligatory or strongly recommended act — no authentic hadith specifically prescribes this.
• Specific rituals tied to the supposed date of the Isra wal-Miraj — the Prophet ﷺ never marked this occasion as a yearly observance.

Voluntary fasting in Rajab is permissible as a sacred month — the Prophet ﷺ fasted in various months outside Ramadan — but it should not be performed with the belief that Rajab fasting has a specific merit over other sacred months unless supported by authentic evidence.

The Conquest of Khaybar

The Battle and subsequent Conquest of Khaybar occurred in Muharram/Safar of the 7th year of Hijra, near the transition to Rajab. The conquest secured the northern Arabian Peninsula for the Muslim community and demonstrated the rapid expansion of Islamic political authority. Historical events in and around Rajab across Islamic history include the commencement of the Islamic conquest of Jerusalem in later centuries, affirming the month's place in the broader tapestry of Islamic history.
