Sunan Ibn Majah, Book 7, Hadith 1772 (In-Book) ⓘ
It was narrated that ‘Abdullah bin ‘Amr Al-Qari said: “I heard Abu hurairah say: ‘No, by the Lord of the Ka’bah! I did not say: “Whoever wakes up in a state of sexual impurity (and wants to fast) then he must not fast.” Muhammad said it.’”
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَمُحَمَّدُ بْنُ الصَّبَّاحِ، قَالاَ حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ عَمْرِو بْنِ دِينَارٍ، عَنْ يَحْيَى بْنِ جَعْدَةَ، عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو الْقَارِيِّ، قَالَ سَمِعْتُ أَبَا هُرَيْرَةَ، يَقُولُ لاَ وَرَبِّ الْكَعْبَةِ مَا أَنَا قُلْتُ، " مَنْ أَصْبَحَ وَهُوَ جُنُبٌ فَلْيُفْطِرْ " . مُحَمَّدٌ ـ صلى الله عليه وسلم ـ قَالَهُ .
