Chapter on Obligation of Fasting
Tahdhīb al-Aḥkām|Volume 4|Book 2|Chapter 1
وَ عَنْهُ عَنْ مُحَمَّدِ بْنِ خَالِدٍ اَلْأَصَمِّ عَنْ ثَعْلَبَةَ بْنِ مَيْمُونٍ عَنْ مَعْمَرِ بْنِ يَحْيَى أَنَّهُ سَمِعَ أَبَا جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ يَقُولُ: »لاَ يَسْأَلُ اَللَّهُ عَزَّ وَجَلَّ عَبْداً عَنْ صَلاَةٍ بَعْدَ اَلْفَرِيضَةِ وَ لاَ عَنْ صَدَقَةٍ بَعْدَ اَلزَّكَاةِ وَ لاَ عَنْ صَوْمٍ بَعْدَ شَهْرِ رَمَضَانَ«.
And from him, from Muhammad ibn Khalid al-Asamm, from Thalabah ibn Maymun, from Mammar ibn Yahya, that he heard Abu Ja’far عليه السلام, peace be upon him, saying:
Imam عليه السلام said: “Allah سبحانه وتعالى, Mighty and Majestic, does not ask a servant about a prayer after the obligatory prayer, nor about charity after zakat, nor about fasting after the month of Ramadan.”
