Believe in Allah's promises and be patient for its fulfillment.

This hadith is about the Prophet Muhammad ﷺ asking a rhetorical question to the dead people in a well. He was reminding them of what their Lord had promised them. This hadith teaches us that even though we cannot hear from those who have passed away, they can still hear us and are aware of what is happening around them. It also reminds us that Allah always keeps His promises and will never forget His promises no matter how long it takes for Him to fulfill it. We should always remember this when we are feeling down or discouraged because Allah will never forget His promise to us either.
