A man who bequeaths all his wealth to be given in charity on his behalf, and it is not carried out until he dies

Al-Awza'i narrated that Umar bin Abd al-Aziz wrote, regarding a man who gave all his wealth in charity to a non-heir and then kept that wealth with himself until he died, that one-third of that wealth is to be given to that non-heir.

Uthman bin al-Aswad said that Mujahid said: Whoever makes a bequest concerning his wealth which he did not carry out until death, it goes to that purpose.
