According to Islamic tradition and the view of the majority of Sunni Muslim scholarship life begins not at the moment of conception nor even in the first stage of development (known as the nutfa, or drop) nor with the presence of the alaqa (that which hangs) or the mudgha, which literally translates to a clump of flesh that looks like chewed skin. Rather, it is the khalqan that describes the moment that it becomes a separate creation. This is the moment that the Archangel Gabriel breathes a soul into the embryo, creating a connection with God and the universe that gives it life. According to the hadith, this moment happens at 120 days or approximately four months into the pregnancy. While Islamic scholars are known for debating scripture at length, the idea that a cluster of cells does not become a person until the soul meets the body is widely agreed upon, a rare moment of almost absolute consensus.
Based on this idea, Muslim scholars largely agree that abortion should be illegal after 120 days into the pregnancy. However, it is the debate surrounding abortion before the 120-day mark where it becomes interesting. According to the Hanafi School of thought one of the four major Sunni schools of Islamic rite and religious law abortion should be permissible so long as there is a sound reason for the abortion. In contrast to todays conservative positions, some Hanafi scholars permitted abortion without any restrictions at any point. Traditionally, reasons have often been a fear of being unable to provide for the child, such as the case with a lack of wet nurses or the presence of other children that depend on the mothers milk. Zina or sex outside of marriage also falls into this category and on the Indian subcontinent, there is a fatwa from the prominent scholar Ahmad Raza Khan that states that abortion is fine for a single mother and maybe even better given social stigma. It is also permissible in cases of rape. Meanwhile, the Shafi school didnt need a reason at all.
Hence the republican position (and the laws proposed for most red states) are far more restrictive than those in states guided by Islam.
The hard core anti-abortion position is clearly based not just on religion but on a single variant of Christianity. Abortion bans such as in Texas and Oklahoma violate the first e amendment by imposing religious-based restrictions on a medical procedure.
