Abu Ishaq reported,

I came to Aswad bin Yazid, who was both a brother and a friend to me, and said, "Abu Amr, tell me what Umm Muiminin told you about the prayer of the Messenger of Allah ﷺ."He said that she said, "He would sleep during the first part of the night and stay awake during the latter part. Sometimes he had need of his wife, then he would sleep before touching water. When the first call to prayer came, he would spring up." She did not say "he stood." "Then he would pour water over himself." She did not say "he performed ghusl," though I know what she meant. "And if he was not in a state of major impurity, he would perform ablution as a man does for prayer."

Ahmad 24708

أبو إسحاق قال

أتيت الأسود بن يزيد وكان لي أخا وصديقا فقلت أبا عمرو حدثني ما حدثتك أم المؤمنين عن صلاة رسول الله ﷺ فقال قالت كان ينام أول الليل ويحيي آخره فربما كانت له حاجة إلى أهله ثم ينام قبل أن يمس ماء فإذا كان عند النداء الأول وثب وما قالت قام فأفاض عليه الماء وما قالت اغتسل وأنا أعلم ما تريد وإن لم يكن جنبا توضأ وضوء الرجل للصلاة
