Praying two Rak‘ahs after performing ablution

“Bilāl, tell me about the act you have done that you deem would be the most rewarding for you with Allāh, for I heard the sound of your footsteps in front of me in Paradise.” Bilāl (ABPWH) replied, “I have not done a deed that I deem would be the most rewarding for me with Allāh, except that I have never performed ablution during any hour of night or day unless I offered prayer with that purification as much as Allāh has written for me to pray.”
