Fulfilling a vow before the condition happens

Q 4 and 5: I made a vow to fast if certain wishes came true. But later I found out that I was wrong about these wishes. Now I no longer care about these wishes. Should I fast to fulfill my vow or not?I vowed to fast if I married the girl I love. But this girl is too young to get married. Perhaps I will not live until the time when she is mature for marriage. Should I fast to fulfill my vow before my wish comes true or wait?

A 4 and 5: You do not have to fulfill your vow before your wish comes true because you stipulated to fulfill your vow if the wish comes true. If it comes true, you will have to fulfill your vow; because the Prophet (peace be upon him) said, Whoever vows to be obedient to Allah should remain obedient to Him; and whoever vows to disobey Allah should not disobey Him. There will be no harm on you if you do not fulfill your vow; (Part No. 23; Page No. 354) because your wish did not come true and hence it is an invalid vow.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
