What is the ruling of Islamic law and the proposed solution for a girl who became pregnant by a man after a six-year relationship, and then he refused to marry her and asked her to abort the fetus after it exceeded its fifth month?

Adultery is an abomination, and its consequences are dire in this world and the Hereafter. He who commits it temporarily loses his faith. The questioner must repent and regret her action, and she should consider meeting Allah with this disobedience. It is not permissible to assault or abort the fetus; rather, it must be protected and raised like other Muslim children.
