The Book of Mosques and Places of Prayer
5/17. Chapter:
Prohibiting one who has eaten garlic, onions, or leeks, and other things that have an offensive odor from coming to the masjid, until that smell has gone away, and such a person should be expelled from the masjid
Sahih Muslim
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَزُهَيْرُ بْنُ حَرْبٍ، قَالاَ حَدَّثَنَا يَحْيَى، - وَهُوَ الْقَطَّانُ - عَنْ عُبَيْدِ اللَّهِ، قَالَ أَخْبَرَنِي نَافِعٌ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ فِي غَزْوَةِ خَيْبَرَ " مَنْ أَكَلَ مِنْ هَذِهِ الشَّجَرَةِ - يَعْنِي الثُّومَ - فَلاَ يَأْتِيَنَّ الْمَسَاجِدَ " . قَالَ زُهَيْرٌ فِي غَزْوَةٍ . وَلَمْ يَذْكُرْ خَيْبَرَ .
Ibn 'Umar reported: The Messenger of Allah (ﷺ) said during the battle of Khaybar: He who ate of this plant, i. e. garlic, should not come to the mosques. In the narration of Zubair, there is only a mention of" battle" and not of Khaybar.
