It is narrated from Sayyiduna Abu Ayyub Ansari (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) would always perform four rak‘ahs at the time when the sun declined. So I asked: O Messenger of Allah! Do you always perform these four rak‘ahs at the time when the sun declines? He (peace and blessings be upon him) replied:“At the time when the sun declines, the gates of the heavens are opened, and they are not closed until the Zuhr prayer is completed. So I wish that a good deed of mine ascends at that time.”I asked: Is there recitation in all these rak‘ahs? He (peace and blessings be upon him) replied:“Yes!”I asked: Is there a separation with salam between them? He (peace and blessings be upon him) replied:“No.”
