Sharik bin Abdullah bin Abi Namir said: I heard Anas bin Malik (may Allah be pleased with him) narrating to us from the Prophet (peace and blessings be upon him) the hadith of the night of the Night Journey: three persons came before revelation came to him, while he (peace and blessings be upon him) was asleep in the Sacred Mosque. The first of them said: "It is he." The middle one said: "He is the best of them."
The last one said: "Take the best of them." That was what happened that night. After that he (peace and blessings be upon him) did not see them until they came another night, in what his heart perceived; his (peace and blessings be upon him) eyes would sleep but his heart remained awake, and likewise the eyes of all the prophets sleep but their hearts remain awake.
