Respect for family ties, Upholding moral values, Following Islamic teachings

The Prophet Muhammad ﷺ taught that marriage between foster siblings is not allowed, as it would be considered the same as marriage between blood relatives. This hadith explains that even though Hamza's daughter was the daughter of his foster brother, he was still not legally permitted to marry her. This teaching emphasizes the importance of respecting family ties and avoiding any kind of inappropriate relationships. It also shows us how important it is to follow Islamic teachings in order to maintain strong family bonds and uphold moral values in society.
