Observe religious obligations even when faced with adversity or doubt from others .

This hadith is about the importance of fasting on the Day of 'Arafat, which is a day that Muslims observe during Hajj. It is narrated by Um Al-Fadl, who was a companion of Prophet Muhammad (ﷺ). On this day, people were doubting whether or not he was observing the fast, so she sent him something to drink as an assurance that he was indeed fasting. This hadith teaches us that it is important to observe religious obligations even when others may doubt us or question our faithfulness. We should strive to be steadfast in our faith and practice even when faced with adversity or doubt from others.
