Q: I had a nephew and in the latter stage of his life he become insane, and long ago he left a trust with me, i.e. an amount of grain. However, due to some difficult circumstances I was forced to use it hoping that I would repay him at a later time if I have the ability and if he is in need. At that time, my nephew had no one to take good care of him or manage his affairs, except for a married sister. However, it was Allah's will that he died before I could return the trust to him, and I considered this trust a debt on me and I performed Hajj on his behalf and also gave Sadaqah (voluntary charity) on his behalf. I intended by that to fulfill the trust, but I do not know whether this is sufficient or if I should give his sister the amount of money that is equal to the grain I took from him. I am now (Part No. 14; Page No. 220) confused, because he is my nephew. Kindly give me your Fatwa in this regard. May Allah reward you with the best.
