Jibrayil ( Alai Salam ) once came to Prophet (S.A.W.S) and said. Allah has given me the knowledge to count Every leaf on earth, Every fish in the sea, Every star in the sky, Every particle of sand and earth, but there's only one thing I can't count. Prophet (S.A.W.S) asked Jibrayil (Alia Salam) what is it?. Jibrayil Alia Salam replied ...... When one of your ummah recites Durood or Salaams to you, The blessing Allah showers upon him becomes impossible for me to count. Subhan Allah Please read Durood at least once now and send this to all the Muslims you know Insha Allah you will get sawab e jariya - Ameen.
