Hadith #1

مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ فَضَّالٍ عَنْ حَجَّاجٍ الْخَشَّابِ قَالَ سَأَلْتُ أَبَا عَبْدِ اللَّهِ ( عليه السلام ) عَنْ رَجُلٍ كَانَ فِي سَفَرٍ فَلَمَّا دَخَلَ الْمِصْرَ جَاءَ مَعَهُ بِشَاهِدَيْنِ فَلَمَّا اسْتَقْبَلَتْهُ امْرَأَتُهُ عَلَى الْبَابِ أَشْهَدَهُمَا عَلَى طَلَاقِهَا قَالَ لَا يَقَعُ بِهَا طَلَاقٌ .

1. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn Faddal from al-Hajj aj al-Khashshab who has said the following: “I once asked abu ‘ Abd Allah, ‘Alayhi al-Salam, about the case of a man who is on a journey and when he enters the city he brings two witnesses, and when his wife comes to the door he asks them to bear witness to the divorce. He (the Imam) said, ’Divorce does not take place in this way.’”
