Arabic hadith text
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا كَثِيرُ بْنُ هِشَامٍ، عَنْ هِشَامٍ الدَّسْتَوَائِيِّ، عَنْ أَبِي الزُّبَيْرِ، عَنْ جَابِرٍ، قَالَ نَهَى رَسُولُ اللَّهِ صلى الله عليه وسلم عَنْ أَكْلِ الْبَصَلِ وَالْكُرَّاثِ . فَغَلَبَتْنَا الْحَاجَةُ فَأَكَلْنَا مِنْهَا فَقَالَ "مَنْ أَكَلَ مِنْ هَذِهِ الشَّجَرَةِ الْمُنْتِنَةِ فَلاَ يَقْرَبَنَّ مَسْجِدَنَا فَإِنَّ الْمَلاَئِكَةَ تَأَذَّى مِمَّا يَتَأَذَّى مِنْهُ الإِنْسُ "
Translation
Jabir reported
The Messenger of Allah (ﷺ) forbade eating of onions and leek. When we were overpowered by a desire (to eat) we ate them. Upon this he (the Holy Prophet) said: He who eats of this offensive plant must not approach our mosque, for the angels are harmed by the same things as men.
