What is the ruling of the Sharia on inheritance disputes that began with false accusations of theft, and ended with the accused waiving his right to his brothers, and then it became clear that the goal was not money but an apology; is he obligated to apologize despite being the wronged party?

A Muslim must take the initiative to end disputes and estrangement between relatives and begin with greetings of peace and reconciliation, for Allah has commanded this in His saying: "So fear Allah and amend that which is between you" and His saying: "But whoever pardons and makes reconciliation - his reward is due from Allah." The Prophet, peace be upon him, clarified that reconciling differences is better than the status of fasting, prayer, and charity, and that corruption between people "is the shaver; I do not say it shaves hair, but it shaves the religion." Furthermore, it is not lawful for a Muslim to abandon his brother for more than three nights, and the best of them is the one who initiates the greeting of peace. If he cannot reconcile by himself, he should seek help from the righteous, for Allah has encouraged striving to reconcile differences, as He Almighty said: "No good is there in much of their private conversation, except for whoever enjoins charity or what is right or reconciliation between people."
