I say, and with God's success: Its residue is pure, and there is no doubt about it, nor is there any dislike; because it is an animal whose meat is eaten, unlike the domestic donkey. Refer to: Talweeh on the Clarification 2: 210, Maraki Al-Falah p. 28, Nafi' Al-Mufti and the Questioner p. 26, and Kanz Al-Daqaiq p. 5, and God knows best.
