It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) (through another chain) that he said: Whoever says these words: 'La ilaha illallah, wallahu akbar, wal-hamdu lillah, wa subhan Allahi kathira, wa la hawla wa la quwwata illa billah' (There is no god but Allah, Allah is the Greatest, all praise is for Allah, I glorify Allah abundantly, and without the enabling of Allah there is neither strength to avoid evil nor power to do good), his sins are forgiven, even if they are more than the foam of the sea. The (previous marfu') hadith of Hatim bin Abi Saghirah is sahih on the condition of Imam Muslim, because such an addition from a trustworthy narrator like him is accepted.
