Yahya related to me from Malik from Ibn Shihab from Abu Salamaibn Abdar-Rahman ibn Awf that Abu Hurayra used to lead them in prayerand would say "Allah is greater" whenever he lowered himself andraised himself. When he had finished he would say, "By Allah, I am theperson whose prayer most resembles the prayer of the Messenger ofAllah, may Allah bless him and grant him peace."
