Good deed #501 – Declare there is no god but Allah
Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said:
مَنْ قَالَ لَا إِلَهَ إِلَّا اللَّهُ وَحْدَهُ لَا شَرِيكَ لَهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ فِي يَوْمٍ مِائَةَ مَرَّةٍ كَانَتْ لَهُ عَدْلَ عَشْرِ رِقَابٍ وَكُتِبَتْ لَهُ مِائَةُ حَسَنَةٍ وَمُحِيَتْ عَنْهُ مِائَةُ سَيِّئَةٍ وَكَانَتْ لَهُ حِرْزًا مِنْ الشَّيْطَانِ يَوْمَهُ ذَلِكَ حَتَّى يُمْسِيَ وَلَمْ يَأْتِ أَحَدٌ أَفْضَلَ مِمَّا جَاءَ بِهِ إِلَّا أَحَدٌ عَمِلَ أَكْثَرَ مِنْ ذَلِكَ وَمَنْ قَالَ سُبْحَانَ اللَّهِ وَبِحَمْدِهِ فِي يَوْمٍ مِائَةَ مَرَّةٍ حُطَّتْ خَطَايَاهُ وَلَوْ كَانَتْ مِثْلَ زَبَدِ الْبَحْرِ
Whoever declares there is no god but Allah, He is one without partner, to Him is the sovereignty and praise and He is powerful over everything one hundred times a day, then he will have the reward of emancipating ten slaves, a hundred good deeds will be recorded for him, a hundred sins will be erased from his record, and he will be guarded from the devil during the day until evening. No one will exceed him except one who recited these words more often. Whoever declares the glory of Allah one hundred times a day, his sins will be erased even if they are like the foam of the ocean.
