Sahih Muslim, Chapter: Faith (Kitab Al Iman)

that when the Messenger of Allah (may peace be upon him) was taken for the Night journey, he was taken to Sidrat-ul-Muntaha, which is situated on the sixth heaven, where terminates everything that ascends from the earth and is held there, and where terminates every- thing that descends from above it and is held there. (It is with reference to this that) Allah said:" When that which covers covered the lote-tree" (al-Qur'an, Iiii. 16). He (the narrator) said: (It was) gold moths. He (the narrator further) said: The Messenger of Allah (may peace be upon him) was given three (things): he was given five prayers, he was given the concluding verses of Sura al-Baqara, and remission of serious Sins for those among his Ummah who associate not anything with Allah.
