It is narrated from Hazrat Abu Dharr (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: There are some words that if a person says them one hundred times after every prayer—namely: Allahu Akbar, Subhan Allah, Alhamdulillah, La ilaha illallah wahdahu la sharika lahu, and La hawla wa la quwwata illa billah—then even if his sins are as much as the foam of the sea, these words will erase them.
