1- We differentiate between two aspects: the technical, legal aspect and the ethical aspect. When I said the intention doesn’t matter, I don’t mean the ethical aspect. I mean the technical aspect. Our intentions are between us and God. Let’s say a man permanently marries a lady, and a week later he divorces her (he had intended to do so from the very start). Technically can he? Yes. Ethically is this right? No of course not. So the point is that when you give your signature, technically it’s a valid transaction regardless of the niyya. The niyya is an ethical issue. So I mentioned this aspect to prove the technical legitimacy of the temporary marriage. Later in video 3 I address the ethical aspect.
2- Mut’ah definitely protects from Zina if properly employed and not abused. Yes some people abuse it, but that’s human nature. People abuse money all the time don’t they? Does this mean money is bad? Remember in videos 1 and 2 I am establishing its legal legitimacy. I am not addressing the ethical aspect. The ethical aspect is addressed in video 3.
3- His wife has the right to know if she stipulated that in the marriage contract. If she didn’t, then by default, technically he does not have to tell her. In some situations a man’s physical needs are not met at home, and if this dilemma is prolonged a man faces immense difficulty, so if he seeks another halal relationship he is not obligated to inform his wife.
