Abu Hurayrah (may Allah be pleased with him) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) said: "Whoever says a hundred times in a day: "La ilāha illallāhu wahdahu la sharīka lah, lahu al-mulku wa lahu al-hamdu wa huwa ‘ala kulli shay’in qadīr" (There is no god but Allah. He is One, and He has no partner with Him; to Him belong the sovereignty and praise, and He is competent over all things); he will have a reward equivalent to that of emancipating ten slaves; a hundred good deeds will be added to his record; a hundred of his sins will be erased; and he will be shielded against the devil on that day till the evening; and no one will exceed him in doing good deeds except someone who says more than that."
