Is a vow dropped if the person to whom it was made forgives the vow?

Question:
May Allah reward you with good. The questioner, Manaa from the Syrian Arab Republic, Damascus, says in this question: I made a vow, and the time to fulfill it arrived, but circumstances prevented me from doing so, and I was unable to fulfill it. Then the person to whom the vow was made came and said to me, “I have forgiven you regarding this vow.” The question is: Is the vow dropped from me, or what should I do? And is an expiation obligatory upon me?

Answer:
There is no doubt that if the vow is an act of obedience, because you vowed to give charity to this woman, who is poor and in need, then this vow is obligatory and you must fulfill it, due to the saying of Allah, Glorified and Exalted is He: “They fulfill their vows,” and His saying: “And let them fulfill their vows.” And the Prophet (peace and blessings be upon him) said: . If she forgives you regarding accepting the vow, then you give it as charity to another person in need. Yes.
