Changing the vow of providing clothes for an old woman who needs money more
A:
Anyone
who vows to perform a specified permissible act, designating a specific thing or a specific kind, they have to fulfill the vow that they made. You vowed to buy some clothes for a poor woman, so you have to do this; it does not suffice to give her money.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
