Begin fasting when seeing a crescent moon at beginning of Ramadan; Stop fasting when seeing a crescent moon at end of Shawwal; Assume 30 days if sky is overcasted; Be mindful & fulfill religious obligations; Be patient in difficult times.

This hadith explains how Muslims should determine when to start and stop fasting during Ramadan. It states that when you see the crescent moon at the beginning of Ramadan, you should begin fasting, and when you see it again at the end of Shawwal, you should stop fasting. If it is cloudy outside so that you cannot see it, then assume that there are 30 days in that month. This hadith teaches us to be mindful of our religious obligations even if we cannot physically observe them due to external factors such as weather conditions. It also encourages us to be patient in difficult times as Allah will always provide a way for us to fulfill our duties towards Him.
