The ruling on one who swears an oath to marry over his wife and then regrets it

The questioner : The questions are outside your scope, outside the scope of affection. A man swore an oath that he would marry over his wife, even if it were after twenty years, but he has regretted it. What should he do?

The Shaykh : As long as the matter is postponed for twenty years, let him be patient, for perhaps he will regret it today and not regret it in the future. But if twenty years pass and he has not married, then it is obligatory upon him to pay the expiation for an oath by feeding ten poor people, or clothing them, or freeing a slave. If he finds no means, he fasts for three days. However, he may say, "I would like to be released from this oath so that I may be at ease." We say, yes, praise be to Allah, Allah has legislated for the human being to be released from an oath, as Allah the Exalted said to the Prophet (peace and blessings be upon him) So now, feed ten poor people, meaning pay the expiation for an oath, as if you had broken your oath.
Then I advise this brother and others among the people not to swear by Allah too often, for many of the exegetes interpreted the saying of Allah the Exalted to mean: do not swear too often. We see many people swear and then regret it. So do not swear if you are determined to do something; do it without an oath if it is good. Or, if you are afflicted with frequent oaths, say "if Allah wills." For if a person says "if Allah wills," he has not broken his oath, even if he made a severe oath and said "if Allah wills." That is, if he said "By Allah," then "By Allah," then "By Allah," then "By Allah, I will certainly do it, if Allah wills," then if he does not do it, there is no breach upon him and no expiation. The Prophet (peace and blessings be upon him) said: Yes.
