Is it permissible for me to be released from my promise to my wife to take her for Umrah after her success, given the severe problems between us and our inability to tolerate each other during travel?

Scholars unanimously agree that fulfilling a promise is recommended (mustahabb) and is one of the virtuous characteristics of a Muslim. Allah the Almighty has commanded His servants to fulfill their covenants, and the Prophet (peace be upon him) warned against breaking promises, considering it a characteristic of hypocrites. Therefore, you should fulfill what you promised your wife, as travel can be a means of resolving problems and fostering intimacy, especially if it is a journey for worship. We advise you to fulfill your promise to your wife, unless it involves great hardship.
