Greetings sister in humanity,
Thank you for sharing your experiences and issues with us so that you can get a advice and counsel from a Muslims perspective regarding your situation. Firstly what we must realise is that just because a person has a Muslim name then it doesn't mean they practice Islam as a way of life as it is meant to be practiced. Nor does it mean they have adequate knowledge of Islam as they should have. So without adopting the principles of Islam into ones life and following worldly and carnal desires then many people of Muslim heritage live as non Muslims neglecting Islam as a daily way of life.
In the case of the man who impregnated you then we cannot make a judgement as to his character however many men will say anything to a woman in order for her to lower her barriers so that he can fulfill his desires. Not only is fornication and adultery forbidden in Islam but anything that leads to it such as "dating" and even private interactions whether via internet, phone or in person are also forbidden as passions and desires are ignited in private interactions which then gradually leads to further evil. The Prophet Muhammad (peace and blessings be upon him) said: “No man is alone with a woman but the Satan will be the third one present.”
Therefore a Muslim must stay away from anything that even comes near to fornication/adultery including private interactions unless the girls Mahram (male family member) is present and this is in order to prevent anything that may lead to evil, immorality and obscenity.
With regards to abortion then Islam regards human life sacred. Almighty Allah says:
“And verily we have honoured the children of Adam” (Surah al-Isra, V.70).
According to Islamic Jurisprudence the soul (Ruh) enters the foetus at 120 days (4 months) from conception. Therefore to abort after 4 months would be totally forbidden. The only exception is if bearing the child would put your life at risk.
Imam Ibn Tamiiyah states:
“Aborting a foetus has been declared unlawful with the consensus of all the Muslim scholars. It is similar to burying an infant alive as referred to by Allah Almighty in the verse of the Qur’an: “And when the female infant, buried alive, will be asked as to what crime she was killed for” (Surah al-Takwir, 8 ) (Fatawa Ibn Tamiyya, 4/217).
So my advice to you is to make it clear to this man that you are going to have the child regardless of what he says because it is a life and it is forbidden to abort it beyond 4 months. You must make it clear to him that he must take responsibility for his actions. So make it clear to him that it is a major sin what he has done according to Islam and that he must now accept the consequences of his actions with regards to how his family will react and also accept the responsibility of a child being born into the world which he must financially take care of. Also make it clear to him that you will have no more physical relations or contact with him nor will you meet privately with him. It may take a while for him to realise the magnitude of this situation but God willing he will eventually come to his senses. If he doesn't then it is only his loss.
With regards to any future with this man then my advice to you is to stop all physical and private contact with him immediately particularly in a private setting like in your home whereby it may be possible for passions to escalate and evil to occur. So if you must meet with him to discuss matters then meet in public places.
Make it clear to him that if he wants to be with you then he must marry you to make your relationship legitimate. Highlight to him the consequences if he were to abandon you and the child and what a detrimental impact it would have on the psychological upbringing of the child not having a father figure whilst growing up.
I would also urge you to look into Islam for yourself. Contact a local Masjid for help and resources for people looking into Islam. Get in touch with knowledgeable Muslim sisters who may help you with your research and situation.
