40 – (weak) Abu Saʿīd al-Khudri reported that the Messenger of Allah ﷺ said:

“Whoever, on retiring to his bed, says: ‘Astaghfiru Allah al-ʿAẓīm alladhī lā ilāha illā Huwa al-Ḥayy al-Qayyūm wa atūbu ilayh (I seek the forgiveness of Allah the Magnificent, besides Whom there is no god, the Ever-Living, the Sustainer, and I repent to Him)’ three times, Allah will forgive his sins even if they are like the foam of the sea, or as countless as the grains of sand in ʿĀlij, or as many as the days of the world.” ⦗79⦘
