“Revelation was being sent down upon the Messenger of Allah (peace be upon him) and his (peace be upon him) head was in the lap of Ali (may Allah be pleased with him). He (Ali) had not performed the Asr prayer until the sun had set. The Prophet (peace be upon him) asked him: ‘Have you prayed?’ He replied in the negative. Upon this, the Prophet (peace be upon him) supplicated to Allah, so the sun was made to rise again for Ali (may Allah be pleased with him) after it had set.”
