Sayyiduna Buraidah Aslami (may Allah be pleased with him) narrates that one day the Noble Prophet (peace and blessings be upon him) came to us and called out three times: O people! Do you know what my example and your example is? The people replied: Allah and His Messenger know best. The Prophet (peace and blessings be upon him) said: My example and your example is like those people who are afraid of an enemy attacking them, so they send someone to find out the situation. As he is on his way, he sees the enemy. He returns to warn his people, fearing that the enemy might reach his people before he can get there and warn them. So he waves his cloth and says: O people! The enemy has come, the enemy is upon you, (beware).
