Chapter 7 | The Binding Consequence of Oath and Vows
2- الْحُسَيْنُ بْنُ مُحَمَّدٍ عَنْ مُعَلَّى بْنِ مُحَمَّدٍ عَنِ الْوَشَّاءِ عَنْ عَبْدِ اللهِ بْنِ سِنَانٍ قَالَ سَمِعْتُ أَبَا عَبْدِ اللهِ يَقُولُ لا يَجُوزُ يَمِينٌ فِي تَحْلِيلِ حَرَامٍ وَلا تَحْرِيمِ حَلالٍ وَلا قَطِيعَةِ رَحِمٍ.
2. Al-Husayn Muhammad has narrated from Mu‘alla’ ibn Muhammad from al-Washsha’ from ‘Abd Allah ibn Sinan who has narrated the following: “I once heard abu ‘Abd Allah , saying, ‘It is not permissible to take an oath to make an unlawful matter lawful, a lawful matter unlawful or to cut off good relations with relatives.’”
