عن أنس بن مالك قال: قال رسول الله صلى الله عليه وسلم: من صلى علي صلاة واحدة صلى الله عليه بها عشرا ومن صلى علي عشرا صلى الله عليه مائة ومن صلى علي مائة كتب الله له براءة من النفاق بين عينيه وبراءة من النار وأنزله الله يوم القيامة مع الشهداء (مجمع الزوائد رقم 17298)

Hazrat Anas (radhiyallahu ‘anhu) reports that Rasulullah (sallallahu ‘alaihi wasallam) said, “Whoever sends salutations upon me once, then as a reward for it, Allah Ta‘ala will send salutations (i.e. reward him and shower His mercy) upon him ten times, and whoever sends salutations upon me ten times, Allah Ta‘ala will send salutations (i.e. reward him and shower His mercy) upon him one hundred times, and whoever sends salutations upon me one hundred times, Allah Ta‘ala will write for him (a certificate of) emancipation, between his eyes, from hypocrisy, and (a certificate of) emancipation from the fire of Jahannum, and Allah Ta‘ala will honor him to be with the martyrs on the Day of Qiyaamah.”
