“I once asked al-Rida’ (a.s.), about the case of a man who at the time of his death made a will to his son and two brothers. The son was present at the time of his making the will but not the brothers. After several days they refused to accept acting as executors of the will for fear from the son and that, they may not be able to work, as they should. A son of an uncle guaranteed their safety when working with the son and with such condition they began the work but the son did not cooperate and they said that they are not responsible for the will. They want to leave it alone and must not be held obligated for anything. Is it permissible for them to leave whatever is in their hand and move out of the task? He (the Imam) said, ‘It is necessary for you to be kind in whatever way you can because you will receive the reward. Perhaps that is to arrive on his son.’”
