Respect family ties and avoid any kind of inappropriate behavior between them

In this hadith, the Prophet Muhammad is teaching us about relationships and marriage. He explains that if two people are related through breastfeeding, they should be treated as if they were related by lineage. This means that it would not be permissible for them to marry each other because of their relationship. This hadith teaches us about the importance of respecting family ties and avoiding any kind of inappropriate behavior between family members. It also reminds us to think carefully before entering into a marriage relationship with someone who may have been breastfed by a relative or close friend.
