Respect your elders and those related by blood or marriage; Treat your relatives with kindness; Be just and fair in all matters; Protect families and maintain strong relationships between them.

This hadith from Abu Hurairah teaches us that it is forbidden for a woman to marry a man who is already married to her aunt. This applies whether the aunt is on the paternal or maternal side of the family. The Prophet Muhammad (peace be upon him) taught us this lesson in order to protect families and maintain strong relationships between relatives. It also serves as a reminder that we should respect our elders and those related to us by blood or marriage. We must remember that Allah has commanded us not only to treat our relatives with kindness but also with justice and fairness in all matters, including marriage.
