Is it permissible for the testator to write in his bequest: "If I am killed by so-and-so, do not demand retaliation (qisas)"?

The questioner : There is a man who was murdered, but the strange thing is that he knew the person who intended to kill him, and he wrote in his bequest that if he died as a result of being killed by so-and-so, they should not demand retaliation (qisas).

The Shaykh : Yes, yes, what is the question?

The questioner : So, is it permissible in his bequest to say, "Do not demand retaliation (qisas) if I am killed by so-and-so"?

The Shaykh : Just as it is permissible for the children of the victim to forgive, it is permissible for him to order his children to forgive. Yes, it is permissible.

The questioner : It is permissible.
