Abu Kurayb, Muhammad ibn al-‘Ala’ al-Hamdani narrated to us: Abu Usamah narrated to us, from al-Walid — meaning Ibn Kathir — who said: Sa’id ibn Abi Sa’id al-Maqburi narrated to me, from his father, from Abu Hurayrah, who said: The Messenger of Allah, peace and blessings be upon him, led us in prayer one day, then he turned away and said: "O so-and-so, will you not improve your prayer? Does the one who prays not look at how he prays? For he only prays for himself. Indeed, by Allah, I see what is behind me just as I see what is before me."
