One who breaks his promise: Will he be held accountable for it on the Day of Resurrection?

Question:
May Allah reward you. He says: Honorable Shaykh, I had resolved to travel to my country permanently because of my low salary, so the son of my employer promised to increase my salary. When a year or more had passed, I asked him about his promise, and he said, "I was only joking with you so that you would not travel." Is that considered a right of mine in the Hereafter if he does not give me what he promised?

Answer:
Fulfilling a promise is prescribed and recommended, and some scholars hold that it is obligatory and that he must fulfill it. In any case, the one who made the promise should carry out what he promised from his own money, from his own money, not from someone else's money. He should fulfill the promise from his own wealth, because he is the one who committed to it. This is what he should do to clear his conscience. Yes.
