The night journey from Makkah to Jerusalem and the ascent through the heavens is affirmed in the Qurʾān (17:1) and in extensive ḥadīth. Its date is another matter: the earliest sīra works place it before the Hijra without fixing a day, and later authorities transmit Rabīʿ al-Awwal, Rajab, and Ramaḍān variants.

Ibn Kathīr surveys the transmitted dates and notes that the soundest early chains name no month at all — a reminder that the observance calendar and the historical record grew up separately.
The 27 Rajab observance became widespread in later centuries and remains the date most communities mark. This entry records the observed date and the disagreement together, rather than resolving what the sources leave open.
