وَعَنْ أَنَسٍ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «مَنْ قَرَأَ كُلَّ يَوْمٍ مِائَتَيْ مَرَّةٍ (قُلْ هُوَ اللَّهُ أَحَدٌ) مُحِيَ عَنْهُ ذُنُوبُ خَمْسِينَ سَنَةً إِلَّا أَنْ يَكُونَ عَلَيْهِ دَيْنٌ» . رَوَاهُ التِّرْمِذِيُّ وَالدَّارِمِيُّ وَفِي رِوَايَتِهِ «خَمْسِينَ مَرَّةٍ» وَلَمْ يَذْكُرْ «إِلَّا أَنْ يَكُونَ عَلَيْهِ دين»

Anas reported the Prophet as saying, 'If anyone recites two hundred times daily, ‘Say, He is God, One’, the sins of fifty years will be wiped out, unless he is in debt.” Tirmidhī and Dārimī transmitted it. The latter’s version has “fifty times”, and he did not mention “unless he is in debt.”
