It is narrated from a man of Banu Amir that once he sought permission from the Prophet Muhammad (peace be upon him) and said, "May I enter?" The Prophet (peace be upon him) said to his maidservant, "Go to him, for he is not seeking permission in a good manner, and say to him that you should say, 'Peace be upon you, may I come in?'" I heard the Prophet (peace be upon him) saying this, so I said, "Peace be upon you, may I come in?" The Prophet (peace be upon him) granted permission and I entered. I asked, "What message have you brought to us?" The Prophet (peace be upon him) said, "I have only brought you a message of goodness, and that is that you worship Allah, who is alone and has no partner, and you abandon Lat and Uzza, perform five prayers in the day and night, fast for one month in the year, perform Hajj to the House of Allah, and take the wealth from your rich and return it to your poor." I asked, "Is there anything that you do not know?" The Prophet (peace be upon him) said, "Allah alone has granted knowledge of goodness, and there are some things that none knows except Allah. They are five things." Then he recited this verse: "The knowledge of the Hour is with Allah alone. He sends down the rain. He knows what is in the wombs. No soul knows what it will earn tomorrow, and no soul knows in which land it will die. Surely, Allah is All-Knowing, All-Aware."
