اَلْحُسَيْنُ بْنُ سَعِيدٍ عَنْ صَفْوَانَ عَنِ اِبْنِ بُكَيْرٍ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ قَالَ:« كُلُّ مَا شَكَكْتَ فِيهِ مِمَّا قَدْ مَضَى فَامْضِهِ كَمَا هُوَ»
Al-Husayn ibn Sa‘id from Safwan from Ibn Bukayr from Muhammad ibn Muslim:
Abu Ja‘far عليه السلام, peace be upon him, said: "Everything you doubt from what has already passed, proceed with it as it is."
