It is narrated from Hazrat Anas (may Allah be pleased with him) that in the blessed era of the Prophet (peace and blessings be upon him), the things I saw, today I do not see any of them except that you say "La ilaha illallah." The narrator says: I asked, O Abu Hamza! Do we not pray? He replied: You perform the Asr prayer at the time of sunset; was this the prayer of the Prophet (peace and blessings be upon him)? However, I have certainly not seen a better time for any doer of deeds than your present time, except if it were the time of the Prophet.
