قال محمد بن الحسن قوله عليه السلام لا بأس بالقران بين السورتين في المكتوبة محمول على انه إذا كان احدى السورتين الحمد وليس في الظاهر انه لا بأس بقرائتهما بعد قراءة الحمد وإذا لم يكن ذلك في ظاهره حملناه على ما قلناه لئلا ينافي ما قدمناه من الاخبار
Muhammad ibn Al-Hasan said: “His عليه السلام statement, peace be upon him; "There is no harm in combining two Surahs in the obligatory prayer," is to be understood as meaning when one of the two Surahs is Al-Hamd. And there is nothing apparent in the wording to suggest that it is permissible to recite two Surahs after the recitation of Al-Hamd. And if it were not apparent in its wording, we would interpret it according to what we have said, so as not to contradict the previous narrations we have mentioned.
