Sunan Abi Dawud, Hadith 2284 ⓘ
Abu Ishaq said “I was with Al Aswad in the congregational mosque. He said “Fathimah daughter of Qais came to ‘Umar bin Al Khattab(may Allaah be pleased with him). (When she narrated the tradition about her divorce) he said “We are not to leave the Book of our Lord and the Sunnah of our Prophet for the statement of a woman, we do not know whether she remembered it or not.”
حَدَّثَنَا نَصْرُ بْنُ عَلِيٍّ، أَخْبَرَنِي أَبُو أَحْمَدَ، حَدَّثَنَا عَمَّارُ بْنُ رُزَيْقٍ، عَنْ أَبِي إِسْحَاقَ، قَالَ كُنْتُ فِي الْمَسْجِدِ الْجَامِعِ مَعَ الأَسْوَدِ فَقَالَ أَتَتْ فَاطِمَةُ بِنْتُ قَيْسٍ عُمَرَ بْنَ الْخَطَّابِ - رضى الله عنه - فَقَالَ مَا كُنَّا لِنَدَعَ كِتَابَ رَبِّنَا وَسُنَّةَ نَبِيِّنَا صلى الله عليه وسلم لِقَوْلِ امْرَأَةٍ لاَ نَدْرِي أَحَفِظَتْ ذَلِكَ أَمْ لاَ .
