Is it permissible for a mother-in-law to retract her waiver of her share of the blood money to the children of the deceased?

Relinquishing a share of blood money is a type of gift (hibah), and retracting a gift is forbidden according to the majority of scholars, based on the Prophet Muhammad's (peace be upon him) saying: "The one who retracts his gift is like a dog that vomits and then returns to its vomit."

However, there is a difference of opinion on two issues:

1. The ruling on a grandmother retracting a gift: Most scholars are of the opinion that a grandmother does not have the right to retract it. 2. The donor retracting the gift before the recipient takes possession: Most scholars, such as the Hanafis and Shafi'is, and some Hanbalis, permit retraction in this case.

Accordingly, it is not permissible for the grandmother to retract her relinquishment of her son's blood money to her grandchildren unless her retraction was before the grandchildren took possession of her share of the blood money.
