Abdullah bin Amr narrated that : the Messenger of Allah (ﷺ) said: “there is not anyone upon the earth who says: ‘None has the right to be worshipped but Allah, and Allah is the Greatest, and there is no might nor power except by Allah, (Lā ilāha illallāh, wa Allāhu akbar, wa lā ḥawla wa lā quwwata illā billāh) except that his sins shall be pardoned, even if they were like the foam of the sea.”
