Sahih Muslim 566
The Book of Mosques and Places of Prayer
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
حَدَّثَنَا هَارُونُ بْنُ سَعِيدٍ الأَيْلِيُّ، وَأَحْمَدُ بْنُ عِيسَى، قَالاَ حَدَّثَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي عَمْرٌو، عَنْ بُكَيْرِ بْنِ الأَشَجِّ، عَنِ ابْنِ خَبَّابٍ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم مَرَّ عَلَى زَرَّاعَةِ بَصَلٍ هُوَ وَأَصْحَابُهُ فَنَزَلَ نَاسٌ مِنْهُمْ فَأَكَلُوا مِنْهُ وَلَمْ يَأْكُلْ آخَرُونَ فَرُحْنَا إِلَيْهِ فَدَعَا الَّذِينَ لَمْ يَأْكُلُوا الْبَصَلَ وَأَخَّرَ الآخَرِينَ حَتَّى ذَهَبَ رِيحُهَا .
Abu Sa'id al-Khudri reported: The Messenger of Allah (ﷺ) along with his Companions happened to pass by a field in which onions were sown. The people stopped there and ate out of that, but some of them did not eat. Then they (Propbet's Companions) went to him. He (first) called those who had not eaten the onions and kept the others (who had taken onions) waiting till its odour vanished.
