اَلْحُسَيْنُ بْنُ سَعِيدٍ عَنِ اِبْنِ أَبِي عُمَيْرٍ عَنْ أَبِي أَيُّوبَ اَلْخَزَّازِ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ: فِي اَلرَّجُلِ يَشُكُّ بَعْدَمَا يَنْصَرِفُ مِنْ صَلاَتِهِ قَالَ فَقَالَ« لاَ يُعِيدُ وَ لاَ شَيْءَ عَلَيْهِ»
Al-Husayn ibn Sa‘id from Ibn Abi Umayr from Abu Ayyub al-Khazzaz from Muhammad ibn Muslim:
Abu Abdillah عليه السلام, peace be upon him, (was asked) regarding a man who has doubt after he has finished his prayer. Imam عليه السلام said: "He does not repeat it, and there is nothing upon him."
