How can one absolve oneself of responsibility for money taken by the father by force after the grandmother's death, and is distributing copies of the Qur’an with the intention of repaying part of the money considered sufficient?

If the questioner did not neglect to inform her father about the trust or hand it over to him, then she is not liable; for a trustee is only liable in cases of transgression or negligence. If she is liable due to her transgression or negligence, then she must hand over the trust to the heirs if her father did not give it to them. Since her father is one of the heirs, his share should be deducted from the amount, and the questioner should pay the remainder. She has the right to complain about her father to whoever can give her justice, in order to reclaim the amount from him and pay it to the heirs.
