Praising God before the Du'a and praying upon Muhammad

One reported hadith relates as follows,

Once a man said, "O God, forgive me and have mercy and have mercy on me!" This was after the man had finished two raka'ats. Prophet Muhammad sal Allahu Alayhi Wa Sallam said, "You have been hasty, O worshipper! When you finish your prayer, then sit down and praise God with the praise that he is worthy of, and pray upon me, then state your du'a..."

Asslamu Alaikaum
