It is narrated from Hazrat Abu Saeed Khudri (may Allah be pleased with him) and Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Allah has chosen four phrases: Subhan Allah, Alhamdulillah, La ilaha illallah, and Allahu Akbar. Whoever says Subhan Allah, twenty good deeds are written for him or twenty sins are forgiven. Whoever says Allahu Akbar and La ilaha illallah receives the same reward. And whoever says Alhamdulillahi Rabbil Alameen from his own side, thirty good deeds are written for him or thirty sins are forgiven.
