The ruling on distributing the estate of a living man to his children before his death

Question:
He says: Honorable Shaykh, may Allah grant you success, some people distribute their estate to their children before they die. Is this permissible? And how do they distribute it? Is it like inheritance? This

Answer:
It is permissible, but it has caused him hardship and he has spent his wealth, leaving him poor, so he has harmed himself. However, if he distributes it to all his children and does not leave any of them out, giving the male the share of two females, then he has been just among them, and there is nothing wrong with it. This is not called inheritance, because inheritance does not occur except after death; this is called a gift.
