Muwatta Imam Malik Book of Divorce, Hadith 2

Yahya related to me from Malik that he had heard that a man came to Abdullah ibn Masud and said, "I have divorced my wife by saying I divorce you eight times." Ibn Masud said to him, "What have people told you?" He replied, "I have been told that I have to part absolutely from her." Ibn Masud said, "They have spoken the truth. A person who divorces as Allah has commanded, Allah makes it clear for him, and a person who obscures himself in error, we make stay by his error. So do not confuse yourselves and pull us into your confusion. It is as they have said."

وَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ رَجُلاً، جَاءَ إِلَى عَبْدِ اللَّهِ بْنِ مَسْعُودٍ فَقَالَ إِنِّي طَلَّقْتُ امْرَأَتِي ثَمَانِيَ تَطْلِيقَاتٍ . فَقَالَ ابْنُ مَسْعُودٍ فَمَاذَا قِيلَ لَكَ قَالَ قِيلَ لِي إِنَّهَا قَدْ بَانَتْ مِنِّي . فَقَالَ ابْنُ مَسْعُودٍ صَدَقُوا مَنْ طَلَّقَ كَمَا أَمَرَهُ اللَّهُ فَقَدْ بَيَّنَ اللَّهُ لَهُ وَمَنْ لَبَسَ عَلَى نَفْسِهِ لَبْسًا جَعَلْنَا لَبْسَهُ مُلْصَقًا بِهِ لاَ تَلْبِسُوا عَلَى أَنْفُسِكُمْ وَنَتَحَمَّلَهُ عَنْكُمْ هُوَ كَمَا يَقُولُونَ .
