Seek permission before fasting when living among a community.

This hadith, narrated by 'Aishah, emphasizes the importance of seeking permission before fasting when living in a community. The Prophet Muhammad was teaching that it is important to be considerate of others and not impose one's own practices on them without their consent. This hadith also teaches us the importance of respecting the customs and traditions of our communities and not going against them without first consulting with those around us. It also encourages us to be mindful of how our actions may affect others, as well as being respectful towards those who are different from us.
