Making a thorough investigation before making a decision

Q: I had indented to marry a lady then during our conversation after couple of months before nikaah I came to know that she is greedy and I fear that she would do the way she likes to do and will not listen to me because I believe she is a professional excusor. I strongly feel that this marriage will not work. I refused once then through a third person we sorted out and tried to re-continue. Now again I am feeling the same situation. Should I go with this marriage or not? I am confused. My family says in this country you don't know people are very different. That lady was married before and got divorce from her husband in a couple of weeks. Please guide me. She said she did istkhara and it was ok. I did but got nothing, no feeling etc. still same.

Different sects

Q: I am very confused when it comes to sects in Islam (e.g. Shia, Sunni, Wahhabi). I live in UK and I see a lot of sects in Muslims here. Myself I belong from Sunni/Sufi background. I like to call myself just a Muslim and try to avoid sects. However, when I try to improve my knowledge of Deen, I get confused by the different opinions. Most of the opinions make sense to me as the scholars from every sect tend to come up with valid evidence. After looking at a YouTube clip of Dr Zakir Naik I got even more confused. He says that Quran is against sects (giving reference to the Quran chapter 6 verse 159- "Indeed, those who have divided their religion and become sects - you, [O Muhammad], are not [associated] with them in anything. Their affair is only [left] to Allah; then He will inform them about what they used to do.”) Now my question is if the Quran doesn’t allow sects. Does that mean everyone who calls themselves Sunni Shia Wahhabi is not following the Quran? And if that’s true, then what is the best way to educate myself?

Rights of parents

Q: Pertaining to Huququl Walidain (Rights of Parents). Inspite of our best and sincere efforts we are unable to fulfil the rights due to our parents. Thoughts do develop in our minds and hearts whether we have missed to fulfil the obligations due yo our parents and these thoughts create a feeling of guilt and an unease feeling in our hearts which really trouble us a lot sometimes. The question is what is the reality of these thoughts and how we could still discharge the rights of our parents who have passed away?

Oral sex

Q: My question is if wife wants to suck husbands private part and she wants to take it in her mouth, is it permissible in Islam. What is the correct way of intercourse?

Meat slaughtered in non Hanafi countries

Q: Is it permissible for us to eat meat slaughtered in non Hanafi countries, such as Malaysia or Saudi Arabia? The reason I'm asking is that we can't be 100% that the meat is halaal according to Hanafi standards. For example, in Malaysia (Shafie) there is a possibility that it would have been slaughtered intentionally without the tasmiyah being pronounced, as this is valid in the Shafie madhab. Also, there is a difference of opinion on how many veins that needs to be cut in the different schools - not all require three veins to be cut like the Hanafis do. Since the asl of meat is hurmah, do these doubts make it impermissible to eat the meat in non-Hanafi countries? If yes, would the ruling be different if a person permanently moves to one of these countries, since it would be difficult to permanently live as a vegetarian there.
