ANSWER:

Your are thinking negatively of Allah and this is a major sin!

You should love for your brother what you love for yourself. If you see your brother got something you like, you should give them dua by saying Allah’humma barik.

Whenever I ask Allah for something exactly the same thing happens with someone other (like friends or family). It feels frustrating and sometimes I avoid them not like I am jealous but i don’t know why… Is it normal?
