 وَ بِهَذَا الْإِسْنَادِ عَنِ الْحَسَنِ عَنِ الْحُسَیْنِ بْنِ أَبِی الْعَلَاءِ عَنْ أَبِی عَبْدِ اللَّهِ ع مَنْ قَرَأَ قُلْ یا أَیُّهَا الْکافِرُونَ وَ قُلْ هُوَ اللَّهُ أَحَدٌ فِی فَرِیضَهٍ مِنَ الْفَرَائِضِ غَفَرَ اللَّهُ لَهُ وَ لِوَالِدَیْهِ وَ مَا وَلَدَ وَ إِنْ کَانَ شَقِیّاً مُحِیَ مِنْ دِیوَانِ الْأَشْقِیَاءِ وَ أُثْبِتَ فِی دِیوَانِ السُّعَ��َاءِ وَ أَحْیَاهُ اللَّهُ سَعِیداً وَ أَمَاتَهُ شَهِیداً وَ بَعَثَهُ شَهِیداً.
1.  Imam as-Sadiq  said: Whoever recites Surah Kafiroon and Surah Tauheed in one of his obligatory prayers, Allah grants  forgiveness  for  him,  for  his  parents  and  for  his children,  and  if  his  name  is  written  in  the  register  of unfortunate and disobedient persons, then after erasing it He writes   in it the register of virtuous and happy people and Allah would grant him the death of a martyr and raise him on the Day of Judgment with the martyrs.
