ANSWER:

No problem in this. As long as the trousers are not skin fit, this is excusable for men. 

Sheikh, you said that you wear jeans & t-shirt when you travel. If I prostrate wearing jeans or other trousers, the shape of my buttock is exposed. Also, if I put my shirt inside of my trouser as part of official dress code, same thing happens even in a standing position wearing loose-fitting trousers. Please guide me as per shariah.

I was calling my wife for fazr prayer last night and she was in deep sleep. I called her few times she said she will get up after few minutes. I was calling her constantly then she got angry and said if I do this she won’t get up(for prayer). She then got up and prayed. Is her statement Kufr? That she said if you do this I won’t get up
