قال الشيخ رحمه الله ولا يصلى في الفنك والسمور ولا تجوز الصلاة في أوبار ما لا يؤكل لحمه
The Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, said: "And one does not pray in garments made of fennec or sable, and it is not permissible to pray in the furs of animals whose meat is not lawful to eat."
