Which is more deserving of kindness: one's own parents or the husband's parents? And what should a wife do if she is kind to her husband's parents, but her own parents become angry?

Your parents have a greater right to your kindness and good deeds than your spouse's parents, due to the saying of the Prophet, peace and blessings be upon him: "Your mother, then your mother, then your mother, then your father." Nevertheless, showing kindness to your spouse's parents is important, as it involves showing kindness to neighbors and relatives, and strengthens the love between spouses. Therefore, one should be keen to show kindness to everyone.
