According to a Hadith recorded in Tabarani on the authority of Abdullah Ibn Abbas (RA) : Abu Hurraira (RA) reports that the Holy Prophet (Pbuh) said:
“Whoever recites the following Durood eighty times immediately after Asr Salaat on Friday, before standing up from his place, Allah will forgive eighty years of sins and grant him the reward equivalent to eighty years of worship.”
Allahumma salli alaa muhammadinin nabiyyil ummiyyi wa-ala aalihi wasallim tasleema
O Allah bless Muhammad, the unlettered Prophet, and his family and grant them best of peace. (Jame Sagheer)
