Whoever recites Salat upon me one time, Allah sends ten mercies upon him. And whoever recites Salat upon me ten times, Allah sends 100 blessings upon him and whoever recites Salat upon me 100 times, Allah will write between both of his eyes that he is free from hypocrisy and the hellfire; and Allah will keep him with the martyrs on the Day of Judgement. (Al-Mujam-ul-Awsat, vol. 5, pp. 252, Hadees 2735)
