1. Mutah is only allowed in one school of thought; Misyar is not allowed in some schools of thought, atleast the one I know of. Never heard of it being practiced. Perhaps, people who practice/believe in these can better answer that why it makes sense. I will keep away from this.
2. How exactly 'Sharia Compliant Financing' works? My initial understanding was that the 'middle' party actually pays off bank without interest in cash or however way, and then, sells the property to customer with profit in fixed installments... which is exactly how a legitimate business is done. What I am hearing now is that bank is involved at the back of it and interest is being paid at atleast one point... That defeats the purpose and if in fact, that is how it is run then, it is not islamic. If it is run how I had initially understood, then, there is no issue and it is perfectly Islamic.
3. We can ask and give same argument on how does a simple act of having nikah done with na-mehram makes the person mehram? it's not that genes changed, it's not that person became a blood relative...
As far as reply to the argument of Ume-zafeera goes, our faith should be that Prophet
was given for nursing because in Allah's eyes, that custom was fine and Allah would have never let that happen to His beloved prophet, had that custom of nursing was not acceptable.
4. The hadeeth is researched in context by a number of scholars, and what I know it is about religious dress themselves that is, when you see people wearing such dress, you recognize that they belong to certain faith... ex: sikh's turban, Rabbai's specific dressing etc. Jeans and paints are considered bad by ignorants.
