Ibn Suhaib reported:Anas was asked about the garlic; he stated that the Messenger of Allah (ﷺ) had said: He who eats of this plant (garlic) should not approach us and pray along with us.
وَحَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا إِسْمَاعِيلُ، - يَعْنِي ابْنَ عُلَيَّةَ - عَنْ عَبْدِ الْعَزِيزِ، - وَهُوَ ابْنُ صُهَيْبٍ - قَالَ سُئِلَ أَنَسٌ عَنِ الثُّومِ، فَقَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ أَكَلَ مِنْ هَذِهِ الشَّجَرَةِ فَلاَ يَقْرَبَنَّا وَلاَ يُصَلِّي مَعَنَا " .
Muslim
