Distribution of assets purchased from the profits of an inherited property that was not distributed immediately after death

Q: I have a question regarding property issue as my father died almost 25 years ago and we are 7 brothers and 5 sisters living with mother Alhamdulillah.

My father left some agricultural land which we have not distributed untill now for some reasons but we have now agreed to divide it according to shariah.

My question is, in the 25 years we have purchased other properties as well like house, plots, car and tractor, etc. from the same agricultural land. How do we divide the other properties which we purchased after our father died?

Accepting the "terms and conditions" on websites without reading them

Q: On many websites when making an account for something or placing an order an option is necessary to be ticked that says, "Do you agree to the terms and conditions?" or "Have you read the terms and conditions?" These terms are always so long that nobody reads them, but we still tick as if we have. Won't this be counted as a sin?

Attending an engagement

Q: I am invited to my 1st cousins engagement. I am the only female in niqaab and I am the only person in my family who is in a Darul Uloom. I don't know if I shouldn't go because I don't want to break the law of Allah Ta'ala or must I go to keep family ties. If I don't go then my family will get really upset with me but doesn't the command of Allah Ta'ala come first?

Performing tawaaf-e-ziyaarat without wudhu

Q: If a person performed tawaf e ziyarat, and then he went back to his home country and he realized that his wudhu was broken because of blood/puss coming out from an old ear infection. Is it obligatory or not to repeat the tawaf-e-ziyarat?

If the person did not repeat tawaf e ziyarat with wudhu, and also did not pay damm/fadiya for this penalty, is this tawaf e ziyarat accepted for Hajj? Is the Hajj valid because there are three obligatory acts (فرض) in Hajj, Niyah/Niyat, Arafat and tawaf-e-ziyarat. 

Performing hajj and tawaaf with impurity on one's ihraam and clothes
