What should my attitude be and how should I help my Hindu brother who is about to get married? Please note that he has stood by me a great deal. He stood by me with regard to paying off my debt. On one occasion when the Hindus were attacking my religion, he stood up to them and defended me. Can I support him materially and stand by him until he is married?.
There is nothing wrong with upholding the ties of kinship with your kaafir brother by giving money and gifts, especially as he has helped you in the past. So you should reciprocate for that. Allaah says (interpretation of the meaning):
“Allaah does not forbid you to deal justly and kindly with those who fought not against you on account of religion nor drove you out of your homes. Verily, Allaah loves those who deal with equity”
And Allaah is the source of strength, may Allaah send blessings and peace upon our Prophet Muhammad and his family and Companions. End quote.
