Al-Azhar textbook: Eating dead Jews, Christians and infidels ‘halal’ if necessary
Religious jurisprudence textbooks for Al-Azhar students address, among other things, the issue of eating dead human beings, quoting Mansour bin Yunus al-Bahuti, a scholar of the Hanbali school of jurisprudence who died 500 years ago, as saying that eating dead Jews, Christians and non-believers is halal (permissible by Islam) if it is a necessity, but non-Muslims are not to eat dead Muslims, even out of necessity.
