Sunan an-Nasa'i, Volume 4, Book 27, Hadith 3439 (DarusSalam) ⓘ
Hammad bin Zaid said: "I said to Ayyub: 'Do you know anyone who said concerning the phrase 'It is up to you' that it is equivalent to three (divorces) except Al-Hasan?' He said: 'No.' Then he said: 'O Allah! Grant forgiveness, sorry.'" Qatadah narrated to me from Kathir the freed slave of Ibn Samurah, from Abu Salamah, from Abu Hurairah, that the Prophet said: "Three." I met Kathir and asked him, and he did not know of it. I went back to Qatadah and told him, and he said: "He forgot."
أَخْبَرَنَا عَلِيُّ بْنُ نَصْرِ بْنِ عَلِيٍّ، قَالَ حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، قَالَ حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، قَالَ قُلْتُ لأَيُّوبَ هَلْ عَلِمْتَ أَحَدًا قَالَ فِي أَمْرِكِ بِيَدِكِ أَنَّهَا ثَلاَثٌ غَيْرَ الْحَسَنِ فَقَالَ لاَ ثُمَّ قَالَ اللَّهُمَّ غَفْرًا إِلاَّ مَا حَدَّثَنِي قَتَادَةُ عَنْ كَثِيرٍ مَوْلَى ابْنِ سَمُرَةَ عَنْ أَبِي سَلَمَةَ عَنْ أَبِي هُرَيْرَةَ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " ثَلاَثٌ " . فَلَقِيتُ كَثِيرًا فَسَأَلْتُهُ فَلَمْ يَعْرِفْهُ فَرَجَعْتُ إِلَى قَتَادَةَ فَأَخْبَرْتُهُ فَقَالَ نَسِيَ . قَالَ أَبُو عَبْدِ الرَّحْمَنِ هَذَا حَدِيثٌ مُنْكَرٌ .
