The wife of Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) (may Allah be pleased with her) said: "O Messenger of Allah, if we give charity to our poor husband or to our nephew who is under our care, will it be accepted from us?" The Prophet (peace and blessings be upon him) said: "You will have a double reward: the reward of charity and the reward of joining the ties of kinship."
