Muwatta Malik, Book 2, Hadith 59 (USC-MSA) ⓘ
Yahya related to me from Malik that as-Salt ibn Zuyayd said, "I asked Sulayman ibn Yasar about a liquid I discovered. He said, 'Wash what is under your garments with water and forget about it.' "
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنِ الصَّلْتِ بْنِ زُيَيْدٍ، أَنَّهُ قَالَ سَأَلْتُ سُلَيْمَانَ بْنَ يَسَارٍ عَنِ الْبَلَلِ، أَجِدُهُ فَقَالَ انْضَحْ مَا تَحْتَ ثَوْبِكَ بِالْمَاءِ وَالْهَ عَنْهُ .
