What must the children of the deceased do to absolve him of responsibility for the donation money he collected to build a clinic, which he was unable to complete, given that he deposited part of it (70,0) into a charitable society with the intention of spending it on other charitable causes for the village without consulting the donors, and lost the remaining part (90,0) in the stock market?

The fundamental principle is the necessity of observing and adhering to the intent of the donors. If the donation was specifically for building a health clinic, it is not permissible to spend it on anything else. However, if it was for general charitable purposes, it is permissible to spend it on any charitable cause needed by the villagers.

If the donation was designated for building a health clinic, the association must be informed. If this is not within its activities, the amount should be returned to the donors or their permission sought.

Placing the remaining amount in the stock market without the donor's permission is considered an infringement that necessitates restitution from the one who did so, and their liability remains. If the deceased's estate is insufficient, his children are obligated to clear his liability. The sin of the deceased and his torment due to his debt vary according to his situation, and Allah may forgive him if he intended to repay. What is required is to return the right, seek forgiveness, and pray for the father.
