وَعَنْ مَيْمُونَةَ رَضِيَ الْلَّهُ عَنْهَا
قَالَتْ: «مَرَّ رَسُولُ الْلَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِشَاةٍ يَجُرُّونَهَا، فَقَالَ: «لَوْ أَخَذْتُمْ إِهَابَهَا؟ «فَقَالُوا: إِنَّهَا مَيْتَةٌ، فَقَالَ: «يُطَهِّرُهَا الْمَاءُ وَالْقَرَظُ»
Narrated (rad): Some people dragging a (dead) goat passed by the Prophet (sallallahu alayhi wa sallam). He told them, “Had you better taken its skin”. They said, “It is dead”. He said, “Water and the leaves of the Acacia tree will purify it”.
