Being concerned about performing Salaah on it's prescribed time

Q: There are various scenarios in which there could be difficulty in me performing Salaah at its prescribed time (of which I have noted four examples below):

a) Being kidnapped and held at gunpoint for a couple of hours

b) The little room in my workplace (which the hierarchy of the company have allowed me to use for Salah during my break times) being occupied by others for a one-off meeting they are having

c) Bleeding from a wound or a cut for a couple of hours

d) Waking up about 15 minutes before Fajar time ends to find that nocturnal emission has taken place and realizing that there is not sufficient time for me to have a ghusl and pray Fajar.

My questions:

1. If I become a person of Taqwa, it is absolutely impossible for any of the four scenarios mentioned above (or similar scenarios) from occurring? (The reason for asking this is that in a previous answer, Muftisaab stated that when Allah says in Surah Talaaq “And whosoever fears Allah and keeps his duty to Him, He will make a way for him to get out”, it refers to any difficulty that a person may be in. Surely this would also relate to difficulties in performing Salaah at its prescribed time).

2. Would I become a kafir if I believe or state that such scenarios could – on the rare one-off occasion – take place even if I fear Allah and keep my duty to Him? Having such a belief would surely mean that a person has rejected the second verse of Surah Talaq? Yes? No?

Bovine gelatin

Q: I have a skin condition on my face which I am suffering from for +/- 10 years. I have tried various treatments but the success is very short. I was told about a natural medication which I researched with good results. I completed 10 days of the course (so far good) before learning that the capsules are made from bovine gelatin. Is it possible to continue the medication? I do not wish to consume something that is not lawful and at the same time I want a cure to my skin condition.

Marital problems

Q: I am really worried with a problem which is very big for me right now. This mail may be big. But for Allah's sake, help me. I asked you a question a few years back regarding my husband taking his office colleague in his car to jummah salaat and dropping her at her home. This was without my knowledge. You said it is not allowed. I've shown the mail to him. The woman and my husband decided not travel. Now again after all this time, I am a mother of 3 boys aged 6 5 and 1 year. I am a stay at home mother. As a wife I fulfill every duty and responsibility of mine to the fullest and as a mother also. My husband and I had a fight over his picking up a neighbor from the Hindu community from his office. I asked him to stop it and he agreed, Promised me. Then two years later I found on his phone a few whatsapp messages saying you are beautiful and some more than friendly chat of whatsapp messages with smiles and lol's. He is 37 now and the girl is maybe 25. He was loving me a lot. Literally he and I shared a very special bond. I felt blessed that Allah has given me a loving and caring husband and three beautiful kids. My family was perfect. Suddenly this girl comes. I asked him to stop taking her in his car as I feel possessive in these things. I don't want another woman to sit in the front seat. He hit me back then. I was pregnant with my 3rd baby. Then he realized and said sorry. I was kept in the dark all this time. He was cheating behind my back. He says he was only friendly with her. Picking her up. Dropping her at home. But why do this without my knowledge. Now he hits me a lot. Says he can leave me (divorce) anytime if I make a fuss out of it. What should I do. I feel lost, suicidal. But I care for my kids. I don't want to hurt them. If something happens to me. They will be left alone in this world. I was hospitalized with all this shock. My BP thyroid sugar levels are high now. I can't bear this anymore. Please help me.
