Bulugh al-Maram 281

Narrated Nu'aim Mujmir (RA):

"I prayed behind Abu Hurairah (RA) and he recited Bismillahir-Rahmanir-Rahim, and then recited Umm-ul-Qur'an (Al-Fatiha) and when he reached walad-dallin, he said Amin; and then said Allahu Akbar, when he prostrated and when he stood up from his sitting position. And when he uttered the Taslim (i.e. As-Salamu 'Alaikum), he said, "I swear by the One (i.e. Allah) in Whose Hand my soul is, my Salat (prayer) resembles most that of Allah's Messenger (ﷺ) than that of anyone among you." [Reported by an-Nasa'i and lbn Khuzaimah].
