Doubts with regards to mistakes in Salaah

Q: I have constant waswas.

1. When I am reciting suras in salah or reciting tashahud sometimes the letters do not come out loud enough so I can hear. Is my Salaah still valid?

2. If I make a mistake in reciting in Salah how far do I go back to correct myself. Do I restart from one whole verse or just from where I made the mistake.

3. In tashahud I didn't say "warahmatullah hi barakatu" properly, so I went back to that bit and recited it again. Is the salaah valid?

Domestic problems

Q: I am having difficulties. I am divorced for the passed six years with 3 kids. I don't have any help from my ex-husband for the kids and I have two brothers. My parents and brothers have hated me a lot. In the passed three years we have become enemies. They don't like my face. They mistreat me and don't let me go to work. All my ways are blocked. I need a wazifa. I want to get a job and they must all agree like before I was working. I am suffering a lot for the passed one year.

False allegations

Q: I saw a video in which aqeedah of deoband was mentioned. The scholar said that in shamaim imdadiya vol 1 pg 37 it is mentioned that it is shirk to distinguish between the worshipper and the worshiped.He said that the deobandis believe that Allah is not different from his creation.What is the correct aqeedah of deoband, please reply?
