Chapter on Apostasy
Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 1|Chapter 54
وَ رَوَى اَلسَّكُونِيُّ عَنْ جَعْفَرِ بْنِ مُحَمَّدٍ عَنْ أَبِيهِ عَنْ آبَائِهِ عَلَيْهِمُ اَلسَّلاَمُ: "أَنَّ اَلْمُرْتَدَّ عَنِ اَلْإِسْلاَمِ تُعْزَلُ عَنْهُ اِمْرَأَتُهُ وَ لاَ تُؤْكَلُ ذَبِيحَتُهُ وَ يُسْتَتَابُ ثَلاَثاً فَإِنْ رَجَعَ وَ إِلاَّ قُتِلَ يَوْمَ اَلرَّابِعِ إِذَا كَانَ صَحِيحَ اَلْعَقْلِ".
Al-Sakuni narrated from Imam Jafar ibn Muhammad Al-Sadiq عليه السلام from his father, Imam Muhammad ibn Ali Al-Baqir عليه السلام, from his forefathers, peace be upon them: "A person who apostasizes from Islam is to be separated from his wife, his slaughtered meat is not to be eaten, and he is to be given an opportunity to repent for three days. If he repents, he is spared, but if he does not repent, he is killed on the fourth day, provided he is of sound mind."
