Hazrat Abu Qatadah narrates that one night he was traveling with the Messenger of Allah (peace and blessings be upon him). During the night, we said, "O Messenger of Allah! If we camp here for a while, it would be good." The Messenger of Allah (peace and blessings be upon him) said, "I fear that you will sleep through the time of prayer. Who will wake us for the prayer?" Hazrat Bilal said, "I will wake you." So the people camped and went to sleep. Hazrat Bilal leaned against his mount and sleep overcame him. When the Noble Prophet (peace and blessings be upon him) woke up, the sun had already risen. The Messenger of Allah (peace and blessings be upon him) said, "O Bilal! What happened to what you said?" He replied, "The sleep that overcame me today has never come to me before." The Messenger of Allah (peace and blessings be upon him) said, "Allah seizes your souls whenever He wills and releases them whenever He wills." Then the Messenger of Allah (peace and blessings be upon him) instructed the companions to disperse for their needs, and they performed ablution. When the sun had risen high, he led them in the Fajr prayer.
