Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 4|Chapter 2
وَ رُوِيَ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ قَالَ: قَامَ رَجُلٌ إِلَى أَمِيرِ اَلْمُؤْمِنِينَ عَلَيْهِ اَلسَّلاَمُ فَقَالَ إِنِّي طَلَّقْتُ اِمْرَأَتِي لِلْعِدَّةِ بِغَيْرِ شُهُودٍ فَقَالَ "لَيْسَ طَلاَقُكَ بِطَلاَقٍ فَارْجِعْ إِلَى أَهْلِكَ".
It was narrated from Muhammad ibn Muslim, from Abu Ja'far Imam Muhammad ibn Ali Al-Baqir عليه السلام, who said: A man stood before the Commander of the Faithful عليه السلام and said: "I divorced my wife during her waiting period (ʿiddah) without any witnesses." Imam عليه السلام replied: "Your divorce is not valid. Return to your wife."
