Our life becomes miserable, when we start feeling jealous of others. Because jealously is the result of lack of emaan. Yes, when Allah has given something to other people, then why do you feel jealousy about it ? This is one of the important reason for breaking of relationships among muslim families. In the first place, I would ask, why do we need to bother about what other person is getting ? Just be happy with what Allah has provided to you. When you see someone with higher standard, just do dua for him and also pray that Allah also gives you the same standard.
