It is narrated from Hazrat Aisha (may Allah be pleased with her) that once the Prophet (peace and blessings be upon him) delayed the Isha prayer so much that most of the night had passed and the people of the mosque had also fallen asleep. Then the Prophet (peace and blessings be upon him) came out and led the prayer and said, "If it were not difficult for my Ummah, the correct time for the Isha prayer would be this."
