How can I deal with my sharp-tongued mother-in-law who lives with us, taking into account my husband's anger if I respond to her, and my desire to move to an independent home despite my husband's financial inability to do so?

We advise you to be patient, for in patience there is relief and victory. Your maternal aunt has a great right over you, so pay no mind to her ill-treatment and continue to be kind to her, seeking the pleasure of Allah the Almighty. Your patience with her is one of the greatest deeds by which you earn reward, and remember that Allah will be your helper as long as you maintain this character.
