Returning the money collected by people to pay Diyah which was remitted

Q: I drove my friends from Tabuk to Al-Madinah Al-Munawwarah and Makkah to perform `Umrah, and on the way we had a car accident. One of my friends died in the accident, and his family demanded me to pay Diyah (blood money). While I was in jail, my brothers collected donations for the Diyah. Fortunately, a royal pardon was issued and the Diyah was waived. Now, after my release, I am asking whether it is permissible for me to take these donations. It is important to note that these donations were collected from different people in different tribes.

A: Since the cause is removed, you are obliged to repay the money, regardless of the amount, to the donors. However, if those donors are aware that the Diyah is waived and they allow you to take the money willingly, there is nothing wrong with you taking it.
