Aqaaid

Q: Is it compulsory to run a madrasah (Islamic Institute)? What is the role of a madrasa?

Q: I belong to a community who believes that majority of Shia are kaafir and want me to call them kaafir too. When I say that I leave this to Allah to decide as I am no one to judge then they call my aqeedah distorted and some even go further by saying that I am an Athiest.

Is it mandatory to call others kaafirs or what does Islam say for people who don’t want to give their verdict?

Q: If a woman passes away unmarried from this world, whom will she marry in jannah:

1. Will she be able to marry any married man in jannah?

2. Will she be able to marry any man who was not her kufu in this world?

Q: How will people be called on the Day of Qiyaamah? By whose names will they be called on the Day of Qiyaamah? 

Q: If a person says "asul" (اسُولُ) instead of "rasul" (رَسُولُ) when trying to recite the shahaadah, has he changed the meaning of the whole sentence to the point of uttering a word of kufr?

Q: What is the meaning of the Quraan being the uncreated word of Allah?

Q:

1. Is it permissible to change and switch between mazhabs more then once? For example, for one to say he's a Hanafi but then decides to become a Shaafi and then become a Hanafi again.

2. Is it permissible for one to adopt a different mazhab because of need. For example, for a Shaafi to become a Hanafi while they are performing tawaaf so if any female has to touch them by mistake their wudhu won't break?

Q: In Bahishti Zewar, there are many masaail that speak about a husband who can have sexual intercourse with a minor. There was 1 certain masa'ala that (if a husband has sexual intercourse with a minor where there is a fear of her vaginal tissues coming together then ghusl is not fard upon her pg. 74 quoted briefly).

Mas'ala was quite graphic and gave me a headache just by thinking about it. My question is, won't that be considered as paedophilia. Does Islam really allow having intercourse with minors. If not then why are these masaail mentioned in Fiqhi books. Your detailed explanation will highly be appreciated.

Q: Is it permissible to read fiction by Muslim authors and the reason for its permissibility or non permissibility?

Q: Some Ulama from the Deobandi school of thought have included the Salafis as a part of Ahlus Sunnah Wal Jamaa'ah and some haven't. They have done this primarily on the basis of Aqeedah. Someone also told me that Moulana Husayn Ahmed Madani had some 'Salafi' beliefs specifically regarding Aqeedah. After some searching I found it to be true.  If that is the case, and their Aqeedah is also correct, why should we then regard them as deviated? Isn't it just another valid ikhtilaaf from many. 

My second question is that, is there Ijmaa' on the compulsion of following a Mazhab, or is it only for the betterment of this pure Deen of ours?
