Hazrat Abu Uthman says that one night the Holy Prophet Muhammad (peace and blessings be upon him) did not come to lead his companions in the Isha prayer until a third of the night remained. Then he came and saw that some people were standing, some were sitting, and some were lying down. He said to them: Since you have been waiting for the prayer, you are in the state of prayer. Among you, those who are standing, sitting, and lying down.
