Is it permissible for me to give my parents from my husband's money with his knowledge and consent? And would I be wronging my husband by doing so? And would my husband be rewarded for it?

It is permissible for you to give your father from your husband's money if he gives it to you willingly and cheerfully, and there is no injustice to him in that. He will be rewarded for his kindness to you and for helping you to show kindness to your father.
