It is narrated from Hazrat Jabir that the Messenger of Allah, peace and blessings be upon him, came one night while his companions were waiting to perform the Isha prayer. He said, "The people have performed the prayer and gone to sleep, and you are waiting for the prayer. From the time you have been waiting to perform the prayer, you are considered to be in prayer. If it were not for the weakness of the weak and the old age of the elderly, I would have delayed this prayer until midnight."
