Hazrat Abu Ayyub Ansari (may Allah be pleased with him) narrated that the Messenger of Allah (peace and blessings of Allah be upon him) said: Whoever recites this phrase — "There is no deity except Allah, He is alone, He has no partner, to Him belongs the dominion and to Him belongs all praise, and He has power over all things" — ten times, it will be as if he has freed one (Arab slave) from among the descendants of Ismail.
