Musannaf Ibn Abi Shayba 33:733

Muhammad ibn Bishr narrated to us, he said: Muhammad ibn ‘Amr narrated to us, he said: Abu Salamah narrated to us that: The morning of the Day of Resurrection, that night will be as long as the length of three nights. Those who fear their Lord will stand and pray, and when they finish their prayer, they will return and sleep until their sides become weary. Then they will stand and pray, and when they finish their prayer, they will wake up looking at the sun from its rising place, and behold, it has risen from its setting place.
