Understand Islamic law and teachings , Allow people freedom in choosing who they want to marry .

This hadith teaches us about the lawfulness of marriage when it comes to sucklings. The Prophet Muhammad (peace be upon him) taught that two or fewer sucklings do not make a marriage unlawful. This means that if someone has been breastfed by the same woman for two or fewer times then they are still allowed to marry each other without any restrictions. This is an important teaching as it allows people to marry who they love without worrying about any legal implications due to their past relationships with their potential spouse's family members. It also shows us the importance of understanding Islamic law in order to ensure our marriages are lawful according to Islamic teachings.
