Isn't It Life-Changing?

Dean Obeidallah: I want to give you a life-changing hadith. When you greet each other properly, Salaamu Alaykum and reply comes Wahlaykum Usala that itself, you earn the mercy of Allah. The angels are standing at the doors of the masajid throughout the world. May Allah Almighty grant us the goodness. He ends with something amazing also on a Friday. Come Friday morning, the angels are writing? Who came first, who came second, who came third, who came fourth, halas.
