I am married, I fulfil all my mothers needs in food, house, bills and even car and necessary things she needs and on top I give her monthly allowance as well for her personal use and savings.. Only one month I was not able to provide her the money she was very angry with me and said it was her righteous money cause she raised me.. Please advise how is thus correct ? Are we obligated to give money to our mother every month? Even though we fulfil everything?
