It is narrated from Sayyiduna Harith bin Hassan that once I passed by an old woman at the place of Rabdhah who had been separated from Banu Tamim. She asked, "Where are you going?" I said, "To the Prophet (peace be upon him)." She said, "Take me with you, I have some work with him." When I reached Madinah, I entered the Prophet's Mosque and the Prophet (peace be upon him) was surrounded by people and a black flag was waving. I asked the people, "Is there something special today?" The people informed me that actually, the Prophet (peace be upon him) is sending Sayyiduna Amr bin Al-As with an army somewhere. I went forward and submitted, "O Messenger of Allah! If you deem it appropriate, then make Hijaz a boundary between us and Banu Tamim, because it used to be so." At this, the old woman jumped forward, her vein of zeal surged, and she said, "O Messenger of Allah! Where will you compel your own Mudar?" I submitted, "O Messenger of Allah! I have brought this old woman with me, how was I to know that she would start arguing with me." I seek refuge in Allah from becoming like that person as the people before said." The Prophet (peace be upon him) asked, "What did the people before say?" I submitted, "Did you ask an informed person?" But the Prophet (peace be upon him) said, "You narrate." Actually, the Prophet (peace be upon him) wanted to hear the whole matter. I submitted, "The people of 'Ad sent one of their men as a delegate. He stayed as a guest of Mu'awiyah bin Bakr for a month. He used to serve him wine and make the singing women sing for him. One day he set out and when he reached the mountains of Mahrah, he said, 'O Allah! I have not come to repay anyone, nor to treat any sick person, so give your servants to drink what You can give, and arrange for Mu'awiyah bin Bakr to serve for a month.' Actually, this was gratitude for the wine he drank at his place for a month. Meanwhile, black clouds came and someone called out, 'Take this cloud full of milk, and do not leave any person of the people of 'Ad thirsty.'"
