Hadith 13:31
Sahih Maqtu' (Al-Albani)
Qatadah reported on the authority of Al Hasan the uttering of the words “Your matter is in your hand” amounts to three pronouncements of divorce.
حَدَّثَنَا مُسْلِمُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا هِشَامٌ، عَنْ قَتَادَةَ، عَنِ الْحَسَنِ، فِي أَمْرُكِ بِيَدِكِ . قَالَ ثَلاَثٌ
