Dr. Zulfiqar Ali Shah, Member of the Executive Committee of the Fiqh Council of North America and the Religious Director of the Islamic Society of Milwaukee, states: “There are two opinions about the use of swine leather. The conservative opinion among the fuqaha’ prohibits such use in all forms and categories. The other opinion permits the use of pig bones, leather, and other parts of the body while prohibiting the consumption of its flesh. The argument is the Qur’anic verse 5 in surat Al-Mai’dah where Allah says: ” Forbidden to you (for food) are: dead meat, blood, the flesh of swine…”
The word used is “the flesh of swine” and not the pig itself. For the last group of scholars using leather jackets, belts, etc. made of pig’s leather will be makruh and not haram, while to some of the contemporary fuqaha’ the chemical process changes the nature of the leather altogether, and therefore, they do not see any problem with using products made of such leather. My recommendation will be to find alternatives even if they are a little more expensive.”
