Allah Ta'ala will not punish one person for the sins committed by another

Q: I’m a non-Muslim. I want to know what does Islam say about Judaism saying if your mom isn’t an Israelite but your dad is, you’re not an Israelite and you were cursed since birth because of the parents’ mistakes and your parents are cursed by God for their mistakes?

Can you please give Quran verses about that? I believe Judaism is unfair for that. Why do Muslims have bara for the Bani Israel i.e. the Jews if Jesus was one?

Eunuchs

Q: What are the conditions of eunuchs in Islam in view of the Holy Qur'an and Hadith if they trust whole heartedly and fulfill such as Kalima, Salaat, Fast, Zakaat, Hajj, etc.? 

Writing a bad review about someone

Q: I have a question about online reviews. I had a bad experience with one of the local Muslim mechanics. The brother fixed 2 problems in my car and after a few days both problems came back. I went to him again and he did something and it came back again. He also charged me just like any other non-Muslim mechanic in town. I thought it is just a bad experience with me and I just lived with the problem because whenever I took the car to him he keeps the car for few days and it is very inconvenient for me without a car.

I took my other car to the same mechanic because he is Muslim and I try to promote Muslim businesses then he fixes a few things in my other car and the same thing happened to this car as well. He replaces the compressor of the AC and when I tried it in summer it worked for only a few days.

I wanted to write a review about him online so others are aware of this before going there but I wanted to ask the question before writing a bad online review. (Does Muslim or non-Muslim matters in this case)
