We talked to one of our relative and they told us that zakah is only entitled for a child who is 13 or above but what I do not understand is how can this be Islam is a religion who teaches us to help each other then how can that be that Islam lets a 13 year old kid have tummy full of food and a kid of 11 be hungry?
بسم الله الرحمن الرحيم
Your mother cannot give her zakah money to you. However, she may give it to the son of your wife. And your brother may give his zakah money to you provided both of you (you and your wife’s son) are eligible to receive zakah. However, if the son of your wife is minor then it is not lawful to spend money or other things owned by him whether it is zakah money on other family members. Yes, if he is grownup then he may spend the money on family after he takes it in his complete possession. However, if both of you are not eligible to receive zakah then it is not lawful for you to receive zakah from anyone.
Allah knows Best!
