وَعَن جَابر
قَالَ: سُئِلَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنَتَوَضَّأُ بِمَا أَفْضَلَتِ الْحُمُرُ؟ قَالَ: «نَعَمْ وَبِمَا أَفْضَلَتِ السِّبَاعُ كُلُّهَا»
When God’s messenger was asked whether ablution might be performed with water which asses had left, he replied, “Yes, and with what all beasts of prey leave.” Baghawi transmitted it in Sharh as-sunna.
