Chapter on the Detailed Explanation of Prayer, Including the Obligatory and Recommended, and What is Permissible and Not Permissible.
وَعَنْهُ عَنْ عَلِيِّ بْنِ اَلْحَكَمِ عَنْ سَيْفِ بْنِ عَمِيرَةَ عَنْ أَبِي بَكْرٍ عَنْ جَعْفَرِ بْنِ مُحَمَّدٍ عَلَيْهِ اَلسَّلاَمُ قَالَ:« إِذَا دَخَلَ وَقْتُ صَلاَةٍ مَفْرُوضَةٍ فَلاَ تَطَوُّعَ»
And from him, from Ali ibn al-Hakam, from Sayf ibn ‘Umayrah, from Abi Bakr:
(Imam) Ja’far ibn Muhammad عليه السلام, peace be upon him, said: "When the time of an obligatory prayer enters, there is no (valid) supererogatory (‘tatawwu’) prayer (to be performed)."
