Sayyiduna Abu Waqid Al-Laithi narrates that when the Messenger of Allah (ﷺ) came to Madinah, the people there used to cut the humps of living camels and the fat tails of sheep (rams). The Messenger of Allah (ﷺ) said: Whatever part is cut from a living animal is unlawful (haram). Yahya ibn Ma'in says: Yahya al-Qattan also narrated from Abdur Rahman ibn Abdullah ibn Dinar.
