What is the Sharia-compliant advice for dealing with feelings of envy and resentment due to comparing one's living situation with that of the co-wife, and the husband's refusal to move to another house?

Jealousy among co-wives is natural as long as it does not escalate to envy and malice. To overcome it, the following is recommended:

1. Thank Allah for His blessings, for gratitude increases and preserves blessings.

2. Look at those who are less fortunate to avoid disparaging Allah's blessings.

3. Remember that envy is an objection to Allah's decree and brings worry and regret.

4. Ignore matters concerning the co-wife to live a happy life with your husband.

5. Occupy your time with beneficial things such as knowledge, studying, and seeking righteous companionship.

6. Remember that life is fleeting and true happiness is achieved through good deeds, pleasing your husband, and purifying your heart.

7. Gently request to move to another residence if possible, to avoid friction with the co-wife.

8. Frequently supplicate for a sound heart, contentment with what Allah has apportioned, and steadfastness in religion.
