Aswad bin Yazid was informed by Hazrat Aisha about the night prayer of the Prophet (peace be upon him), saying that the Prophet (peace be upon him) would sleep in the early part of the night and wake up in the last part of the night. Then, if he felt a need towards his wife, he would fulfill his need, then before touching water, he would stand up. When the first call to prayer was given, the Prophet (peace be upon him) would go quickly and pour water over his body, and if he was not in a state of major impurity, he would only perform the ablution for prayer and would offer two units of prayer.
