Abu Huraira (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings of Allah be upon him) said one day after leading the prayer: "O so-and-so! Why do you not perform your prayer properly? Does the one who prays not see how he is praying? Indeed, he prays for his own benefit. By Allah, I see those behind me just as I see those in front of me."
