Narration On Mairaj From Anas Bin Malik (rta)
According to Ghamidi Sahab, this incident narrated by Anas (rta) is not related to the Mairaj that is mentioned in Quran Surah Bani-Israel. They were four separate incidents/experiences of the Prophet Muhammad (Sws). Two of them are mentioned in Surah Najam, third is mentioned in Surah Bani-Israel and the fourth one is mentioned in Sahih Bukhari as referenced by you in your question ( https://sunnah.com/bukhari:7517 ). It is obvious that Anas (rta) has narrated this experience that he must’ve heard from the Prophet (sws) himself or from someone else. For comments of Ghamidi Sahab on these four independent experiences , please refer to the following video ( and from 29:33 onward for commentary on this specific narration ): Discussion 39572 • Reply 39573
