Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates that we waited for the Messenger of Allah (peace be upon him) for the 'Isha prayer until about midnight. Then the Prophet (peace be upon him) came and led us in prayer and said: "Remain seated in your places. Indeed, people have gone to sleep. Indeed, from the time you have been waiting for the prayer, you have been in prayer continuously. And if it were not for the weakness of a weak person, the illness of a sick person, and the need of a needy person, I would have delayed this prayer until midnight." This is the narration of Bundar.
