Hadith #1

حَدَّثَنِی مُحَمَّدُ بْنُ الْحَسَنِ قَالَ حَدَّثَنِی مُحَمَّدُ بْنُ الْحَسَنِ الصَّفَّارُ عَنِ الْعَبَّاسِ بْنِ مَعْرُوفٍ عَنْ سَعْدَانَ بْنِ مُسْلِمٍ عَنْ عَبْدِ اللَّهِ بْنِ سِنَانٍ عَنْ أَبِی عَبْدِ اللَّهِ ع قَالَ سَمِعْتُهُ یَقُولُ مَنْ صَلَّی أَرْبَعَ رَکَعَاتٍ یَقْرَأُ فِی کُلِّ رَکْعَهٍ بِ قُلْ هُوَ اللَّهُ أَحَدٌ خَمْسِینَ مَرَّهً لَمْ یَنْفَتِلْ بَیْنَهُ وَ بَیْنَ اللَّهِ عَزَّ وَ جَلَّ ذَنْبٌ إِلَّا غَفَرَ لَهُ.
