Buraida told how one morning God’s Messenger called Bilal and said, "What did you do to get to paradise before me? I have never entered paradise without hearing the rustling of your garments in front of me.” He replied, "Messenger of God, I have never called the adhan without praying two rak'as, and no impurity has ever happened to me without my performing ablution on the spot and thinking that I owed God two rak'as.” God’s Messenger said, "It is because of them.” Tirmidhi transmitted it.
