Have faith in Allah’s Messengers .

This hadith is about how the people of Mecca asked for a sign from Allah's Messenger, and he showed them a miracle by splitting the moon in two. This event is known as "the splitting of the moon" and it was seen by many people at that time. It serves as an example of how powerful Allah's Messenger was, and how his miracles were undeniable proof that he was sent by God. The lesson we can learn from this hadith is that we should always have faith in Allah's messengers, no matter what they do or say. We should also remember that miracles are possible with God's help, so we should never doubt His power or His messengers.
