Theory of evolution

Q: What is the status of someone, who in an attempt to reconcile the theory of evolution with the Islamic narrative of human origins, states that homo sapiens (modern humans) descended from other hominid species (all the while believing that all of this happened by Allah's Will and Power). Thereafter, these homo sapiens went extinct (died off) and Allah created Adam (Alayhis Salaam) - a special, direct, and miraculous creation - and we are all descendants of Adam (Alayhis Salaam). Is this belief kufr? Is this person a kafir (disbeliever)?

Making enquiries regarding the aqaaid of the person one wishes to marry

Q: I am engaged but I am unclear about the boys deeni committments. I think he doesn't know much about deen as he says that he is a simple Muslim and thats it. Can you please guide me as to what questions should my family ask him in order for the the nikah to be valid? Is it necessary to question his aqaaid if he offers namaaz?

Knowledge of the unseen

Q: I am asking this question on behalf of a friend. He wants to know if there is any dua that can be read to find out if his wife is having an affair with her sisters husband. How can one see if they are still having sexual intercourse whenever she goes for holiday to her sisters house?
