<b>Guidance from the Hadith:</b><br> 1) Whoever vows to do something good should fulfill his vow and not break it. But if a person vows to commit a sin, his vow is not valid, and he should make expiation like that for a broken oath.<br> 2) A vow over something good should be fulfilled. It is disliked for a person, however, to commit himself to a vow. About making a vow, the Prophet (may Allah’s peace and blessings be upon him) said: “It does not bring good. Indeed, it is only a means by which something is extracted from the miserly.” [Narrated by Muslim]
