Promised to marry her if she embraced Islaam

I am the undersigned ‘Abdul-Qaadir, and I am 25 years of age. I wish to ask regarding a Christian woman who is 25 years of age; I promised her that when she becomes a Muslim I will marry her, and now she has embraced Islaam should I marry her, keeping in mind that my father is strongly against this marriage [taking place]?

Renting a trading establishment to a bank which deals with ribaa

I own [some] stores located on al-Hijaaz Road, and the National Bank has offered to rent them; [so] since this bank is amongst those banks which deal with ribaa, would it be permissible for me to rent [these stores] to this bank and those like it which deal with ribaa? Please provide us with a fatwa, and may Allaah reward you [well].

I was gifted a camera and began [by] filming an entire film; however, I [then] heard that photographers [and filmmakers] will be punished the most severely on the Day of Resurrection, so what should I do? And should I begin by burning these [films and] pictures? And how about [filming and] taking pictures of nature – without any human beings?
