Hadith 543

Qais b. ‘Asim said that when he accepted Islam the Prophet commanded him to bathe with water and lote-tree leaves. Tirmidhi, Abu Dawud and Nasa’i transmitted it.

وَعَن قيس بن عَاصِم: أَنَّهُ أَسْلَمَ فَأَمَرَهُ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنْ يَغْتَسِلَ بِمَاءٍ وَسِدْرٍ. رَوَاهُ التِّرْمِذِيُّ وَأَبُو دَاوُدَ وَالنَّسَائِيُّ
