First Blood. Purity, Edibility, and the Independence of Islamic Jurisprudence

The first stages of the development of Mohammedan religious law are characterized by a far reaching reception of the most varied elements; its substratum is to a great extent not originally Islamic, let alone Koranic. Also, although/igA al-tahara is unquestionably concerned with the ritual effects of animal blood, it is far more concerned with human blood and bleeding, and jumping the barrier from a verse concerning animal blood to a purity system preoccupied with human blood does not sound particularly likely.
