Chapter: The beginning of the time for Maghrib when the sun sets
A'isha reported: The Apostle of Allah ( صلی اللہ علیہ وسلم ) one night delayed (observing the 'Isya' prayer) till a great part of the night was over and the people in the mosque had gone to sleep. He (the Holy Prophet) then came out and observed prayer and said: This is the proper time for it; were it not that I would impose a burden on my people (I would normally pray at this time). In the hadith transmitters by 'Abd al-Razzaq (the words are): Were it not that it would impose burden on my people.
