We made no transgression but Khaybar was conquered. We, the Companions of the Messenger of Allah ﷺ, fell upon this plant. i e. garlic. because the people were hungry. We ate it to our heart's content and then made our way towards the mosque. The Messenger of Allah ﷺ sensed its odour and he said: He who takes anything of this offensive plant must not approach us in the mosque. The people said: Its (use) has been forbidden; its (use) bu been forbidden. This reached the Messenger of Allah ﷺ and he said: O people, I cannot forbid (the use of a thing) which Allah has made lawful, but (this garlic) is a plant the odour of which is repugnant to me.
أَنْ فُتِحَتْ خَيْبَرُ فَوَقَعْنَا أَصْحَابَ رَسُولِ اللَّهِ ﷺ فِي تِلْكَ الْبَقْلَةِ الثُّومِ وَالنَّاسُ جِيَاعٌ فَأَكَلْنَا مِنْهَا أَكْلاً شَدِيدًا ثُمَّ رُحْنَا إِلَى الْمَسْجِدِ فَوَجَدَ رَسُولُ اللَّهِ ﷺ الرِّيحَ فَقَالَ مَنْ أَكَلَ مِنْ هَذِهِ الشَّجَرَةِ الْخَبِيثَةِ شَيْئًا فَلاَ يَقْرَبَنَّا فِي الْمَسْجِدِ فَقَالَ النَّاسُ حُرِّمَتْ حُرِّمَتْ فَبَلَغَ ذَاكَ النَّبِيَّ ﷺ فَقَالَ أَيُّهَا النَّاسُ إِنَّهُ لَيْسَ بِي تَحْرِيمُ مَا أَحَلَّ اللَّهُ لِي وَلَكِنَّهَا شَجَرَةٌ أَكْرَهُ رِيحَهَا
