There is no god worthy of worship except Allah. He is Alone and He has no partner whatsoever. To Him Alone belong all sovereignty and all praise. He is over all things All-Powerful.

Abū Hurayrah (raḍiy Allāhu ʿanhu) narrates that the Messenger of Allah ﷺ said: “He who says [the above] 100 times in a day will have a reward equivalent to that of freeing 10 slaves. A 100 good deeds will be recorded to his credit, and a 100 of his sins will be blotted out from his scroll. He will be safeguarded against Shayṭān on that day till the evening; and none will surpass him in doing better good deeds except someone who has recited these words more often than him.” (Bukhārī 3293) The Messenger of Allah ﷺ said: “Whoever says [the above] 100 times in the morning and evening, none will surpass him in doing better good deeds except someone who has recited it more than him.” (Nasā’ī in al-Sunan al-Kubrā 10410)
