I have a question if cursed effective in Islam. When I was young at 20’s of age my uncle wish me to be arrange to his son which my first cousin, he said he prepared me than others and he wished for that before he died he was sick that time, all the family members agreed except my mother and my father cannot say Yes directly. As my own decision I refused, because all I wanted that time is to help my family and sisters sending their school. I work hard for my family. Time goes by were getting matured and ready for relationship. Since then, Id been in serious relationships, of course I wish one of this be the ONE, but never in successful. So many men try to courtship me, I have a nice job Alhamdulillah, and I raised my sister’s school and got nice job also. I am thinking now my relationship failures are caused by the cursed. Maybe my uncle families get angry to me and cursed not to get a relation anymore.
How can I repent to them if yes?
