As long as you don’t show or express this anger and hatred, you are not at sin!
However, a Muslim excels to the highest level possible  in order to be with the Prophet salla Allahu alaihi sa sallam in paradise. Therefore, be always the first to call them and to reach out and never allow anyone to call youl first. Don’t let anything penetrate your heart or fill it with negative feelings and move one. Life is shorter than to be wasted in such negative thoughts.

My sisters don’t communicate with me or with each other properly, I have to ALWAYS contact them first. My mother doesn’t follow Islam and starts hateful speech when I nicely refuse to do something unislamic. I feel hatred towards them coz it’s always a BURDEN to handle them but I force myself to talk 2 them for Allah’s sake alone. Am I bad for this hatred and anger towards them bt I do it 4 Allah?

Once I invited a relative,with whom family terms were not good because of minor dispute long back,for a wedding at our home but they didn’t show up. Next year we had another marraige for which we sent them invitation again they didn’t come. This year too we had another marraige of a family member but this time I didn’t sent them invite.Is it breaking kinship from my side?

My question is what if the parents dont want their grown up children to meet thier siblings means one parental (both sides) uncles and aunts and first cousins. Because of their own personal issues. Whats on the person then? What should one do.
