Arabic hadith text
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 "
