It is narrated from Sayyiduna Ibn Amr, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: "Whoever on the face of the earth says: La ilaha illallah, Allahu Akbar, Alhamdulillah, Subhanallah, and La hawla wa la quwwata illa billah, these phrases will be an expiation for all his sins, even if they are as much as the foam of the sea."
