Show kindness and respect towards relatives regardless of their distance from you.

This hadith teaches us about the permissibility of allowing a paternal uncle who was breastfed by the same woman as oneself into one's home, even if the man did not breastfeed them. This is because breastfeeding creates a bond between two people and makes them family in Islam. The Prophet Muhammad (PBUH) showed his compassion and mercy when he allowed 'Aishah's paternal uncle to enter her house despite her initial refusal due to him not being her direct milk-brother. He also showed his love for 'Aishah when he said "May your hands be rubbed with dust" or "May your right hand be rubbed with dust!" which is an expression of endearment in Arabic culture. We can learn from this hadith that we should show kindness and respect towards our relatives, no matter how distant they may seem, as they are still part of our family in Islam.
