One Durood, Ten Rahmats

Rasulullah (Sallallahu alaihi wasallam) said: “Allah Ta’ala sends ten Rahmats to the person who sends one Durood to me.” (Muslim – Mishkaat)

This is in view of the Divine Declaration: “Whoever produces one good deed, he will receive ten times more in reward.” Thus, whoever sends Durood to Rasulullah (Sallallahu alaihi wasallam) one time, then in accordance with the Glad Tiding, Allah Ta’ala sends down ten times Rahmat to him. (Mazaahir-e-Haq)
