Sunan Ibn Majah, Book 1, Hadith 637 (In-Book) ⓘ
It was narrated that 'Abdullah bin Salamah said: "I entered upon 'Ali bin Abu Talib and he said: 'The Messenger of Allah used to go to the lavatory and relieve himself, then come out, and he would eat bread and meat with us and recite Qur'an, nothing stopped him' or perhaps he said: 'prevented him from doing so except sexual impurity.'"
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ عَمْرِو بْنِ مُرَّةَ، عَنْ عَبْدِ اللَّهِ بْنِ سَلِمَةَ، قَالَ دَخَلْتُ عَلَى عَلِيِّ بْنِ أَبِي طَالِبٍ فَقَالَ كَانَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ يَأْتِي الْخَلاَءَ فَيَقْضِي الْحَاجَةَ ثُمَّ يَخْرُجُ فَيَأْكُلُ مَعَنَا الْخُبْزَ وَاللَّحْمَ وَيَقْرَأُ الْقُرْآنَ وَلاَ يَحْجُبُهُ - وَرُبَّمَا قَالَ وَلاَ يَحْجُزُهُ - عَنِ الْقُرْآنِ شَىْءٌ إِلاَّ الْجَنَابَةُ .
