Hazrat Jibrail [Alayh Salam] once came to Prophet Muhammad صلی اللہ علیہ وآلہ وسلم and said "Allah Almighty has given me the knowledge to count every leaf on earth, every fish in the sea, every star in the sky and every particle of sand on earth, but there's only one thing I cant count." Prophet Muhammad (PBUH) asked "What is it?", Jibrail(A.S) replied, "When one of Your (PBUH) )Ummati recites Durood or Salaams to You (PBUH), the blessings Allah Almighty showers upon him become impossible for me to count." SubhanAllah
Sayyiduna Abu Dardah ( Razi Allahu Ta'ala Anhu ) reported: the Holy Prophet (Sallal Laahu Alaihi Wasallam) said, "Whoever recites durood on Me in the morning
ten times and in the evening ten times, for him shall be My intercession on the day of Qiyamah."
"By Him in whose Hands My life is, none of you will have faith till he loves Me more than his father and children."
-- Prophet Muhammad (صلی اللہ علیہ وآلہ وسلم ), narrated by Abu Huraira (RaziAllahu Anhu)
