Praise be to Allah.
We advise you to forget what happened in the past between you and your uncle. We think that you have given the matter more attention than it deserves. Your uncle’s entering the house without asking permission is not permissible for him, even if he is entering the house of his sister. Seeking permission is obligatory in his case, and your father’s approval of your uncle visiting his house is what matters. He agreed to that, as is suggested by the fact that he continued to visit him for such a long time. The fact that you did not take the exam that year and you failed is something for which you must bear responsibility. Most Muslim families have their problems, and the wise man is the one who knows how to deal with these problems and tries to solve the problems or reduce them. We do not think that your giving up your studying for the exam served any purpose, and you must bear responsibility for that. You should not keep on thinking about what is past, for that will cause psychological problems for yourself and your family. Forget about it and get on with your work; seek the help of Allaah and uphold the ties of kinship and give advice to those who are erring. Do not pay any attention to what the shaytaan makes attractive to you, namely the idea of bringing a case against your uncle and taking financial compensation from him. In addition to the fact that this case may fail in court, it will cause more rifts in your family, and we would not like you to be the cause of that. Mercy should prevail over anger and the desire for revenge. We ask Allaah to open your heart and to bring you and your family together in goodness.
And Allaah is the Source of strength.
