Sahih Muslim 2691
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ سُمَىٍّ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " مَنْ قَالَ لاَ إِلَهَ إِلاَّ اللَّهُ وَحْدَهُ لاَ شَرِيكَ لَهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَىْءٍ قَدِيرٌ . فِي يَوْمٍ مِائَةَ مَرَّةٍ . كَانَتْ لَهُ عَدْلَ عَشْرِ رِقَابٍ وَكُتِبَتْ لَهُ مِائَةُ حَسَنَةٍ وَمُحِيَتْ عَنْهُ مِائَةُ سَيِّئَةٍ وَكَانَتْ لَهُ حِرْزًا مِنَ الشَّيْطَانِ يَوْمَهُ ذَلِكَ حَتَّى يُمْسِيَ وَلَمْ يَأْتِ أَحَدٌ أَفْضَلَ مِمَّا جَاءَ بِهِ إِلاَّ أَحَدٌ عَمِلَ أَكْثَرَ مِنْ ذَلِكَ . وَمَنْ قَالَ سُبْحَانَ اللَّهِ وَبِحَمْدِهِ فِي يَوْمٍ مِائَةَ مَرَّةٍ حُطَّتْ خَطَايَاهُ وَلَوْ كَانَتْ مِثْلَ زَبَدِ الْبَحْرِ " .
Abu Huraira reported that the Messenger of Allah (ﷺ) said: Whoever says one hundred times in a day, There is no god but Allah alone, with no partner. To Him belongs dominion and praise, and He has power over all things, will have the reward of freeing ten slaves; one hundred good deeds will be recorded for him, one hundred sins erased, and he will be protected from Satan that day until evening. No one will bring anything better than this, except one who does more. Whoever says one hundred times in a day, Glory and praise be to Allah, his sins will be erased, even if they are like the foam of the sea.
