Is the deceased's wealth zakat due before its distribution, or after a year has passed for each heir's share?

What the husband leaves behind in terms of money and other assets becomes the property of the heirs immediately upon his death. There is no need to wait for a full year to pass before paying zakat. The wealth is distributed according to Sharia, and each heir examines their share. If their share reaches the nisab (minimum threshold) by itself, or by adding cash, gold, silver, or trade goods to it, they must pay zakat on it after a full year has passed since they acquired ownership of it.
