Renouncing part of one's right, then retracting one's statement: What is the ruling on that?

Question:
He says: Honorable Shaykh, may Allah grant you success. If the owner of a right is satisfied with part of his right and takes it, then says, "I do not permit it in the sight of Allah regarding what remains owed to him," and speaks about it in gatherings, what is the ruling on that?

Answer:
If he is satisfied, he has no claim, because he was satisfied, took what he took, and renounced part of his right by his own satisfaction, without anyone forcing him, so he has no claim. However, if this is in the context of denial, where he denied and settled, saying, "I will take what was given to me, and I forgive the rest," then this settlement is from denial, not from acknowledgment. It has been stated previously that the settlement of the one who lies among them is not valid regarding his right; the settlement of the one who lies among them is not valid regarding his right. Yes.
