During the holy battle of Khaibar the Prophet ﷺ said, "Whoever ate from this plant (i.e. garlic) should not enter our mosque."  

أَنَّ النَّبِيَّ ﷺ قَالَ فِي غَزْوَةِ خَيْبَرَ مَنْ أَكَلَ مِنْ هَذِهِ الشَّجَرَةِ يَعْنِي الثُّومَ فَلاَ يَقْرَبَنَّ مَسْجِدَنَا  

A man asked Anas, "What did you hear from the Prophet ﷺ about garlic?" He said, "The Prophet ﷺ said, 'Whoever has eaten this plant should neither come near us nor pray with us."  

سَمِعْتَ نَبِيَّ اللَّهِ ﷺ فِي الثُّومِ فَقَالَ قَالَ النَّبِيُّ ﷺ مَنْ أَكَلَ مِنْ هَذِهِ الشَّجَرَةِ فَلاَ يَقْرَبْنَا أَوْ لاَ يُصَلِّيَنَّ مَعَنَا  

The Prophet ﷺ said, "Whoever eats garlic or onion should keep away from our mosque or should remain in his house." (Jabir bin ʿAbdullah, in another narration said, "Once a big pot containing cooked vegetables was brought. On finding unpleasant smell coming from it, the Prophet ﷺ asked, 'What is in it?' He was told all the names of the vegetables that were in it. The Prophet ﷺ ordered that it should be brought near to some of his companions who were with him. When the Prophet ﷺ saw it he disliked to eat it and said, 'Eat. (I don't eat) for I converse with those whom you don't converse with (i.e. the angels).  

أَنَّ النَّبِيَّ ﷺ قَالَ مَنْ أَكَلَ ثُومًا أَوْ بَصَلاً فَلْيَعْتَزِلْنَا أَوْ قَالَ فَلْيَعْتَزِلْ مَسْجِدَنَا وَلْيَقْعُدْ فِي بَيْتِهِ وَأَنَّ النَّبِيَّ ﷺ أُتِيَ بِقِدْرٍ فِيهِ خَضِرَاتٌ مِنْ بُقُولٍ فَوَجَدَ لَهَا رِيحًا فَسَأَلَ فَأُخْبِرَ بِمَا فِيهَا مِنَ الْبُقُولِ فَقَالَ قَرِّبُوهَا إِلَى بَعْضِ أَصْحَابِهِ كَانَ مَعَهُ فَلَمَّا رَآهُ كَرِهَ أَكْلَهَا قَالَ كُلْ فَإِنِّي أُنَاجِي مَنْ لاَ تُنَاجِي وَقَالَ أَحْمَدُ بْنُ صَالِحٍ عَنِ ابْنِ وَهْبٍ أُتِيَ بِبَدْرٍ قَالَ ابْنُ وَهْبٍ يَعْنِي طَبَقًا فِيهِ خُضَرَاتٌ وَلَمْ يَذْكُرِ اللَّيْثُ وَأَبُو صَفْوَانَ عَنْ يُونُسَ قِصَّةَ الْقِدْرِ فَلاَ أَدْرِي هُوَ مِنْ قَوْلِ الزُّهْرِيِّ أَوْ فِي الْحَدِيثِ
