Sahih Muslim Book 1, Hadith Number 312.

Chapter : Night journey of the Messenger of Allah (may peace be upon him) to Heaven and the prayer made obligatory.

Anas b. Malik, while recounting the Night journey of the Holy Prophet (may peace be upon him), from the mosque of Ka’bah, reported: Three beings (angels) came to him in the mosque of the Ka’bah, while he was sleeping in the sacred mosque before it (the Command of Night Journey and Ascension) was revealed to him. The rest of the hadith is narrated like that of Thabit. However, some portions have occurred before and some of them have occurred after; some have been added and some deleted.
