Hadhrat Aus bin Aus (Radhiallahu Anhu) reports that Rasulullah (Sallallahu Alaihi Wasallam) said: The most virtuous of days is the day of Jum’uah. Therefore, recite abundant durood upon me on this day, for indeed your durood are presented to me.
Hazrat Abdullah bin Amr bin Aas (radhiyallahu ‘anhuma) reported, “Whoever sends salutations upon Nabi (sallallahu ‘alaihi wasallam) once, Allah Ta‘ala and His angels will send seventy mercies and blessings upon him in return of his one Durood. Hence, whoever wishes to increase his Durood should increase it, and whoever wishes to decrease his Durood should decrease it (i.e. if he wants to earn great rewards, then he should increase his Durood).”
