Narrated AbuHurayrah:
The Apostle of Allah (peace_be_upon_him) used to sit with us in meetings and talk to us. When he stood up we also used to stand up and see him entering the house of one of his wives. One day he talked to us and we stood up as he stood up and we saw that an Arabi (a nomadic Arab) caught hold of him and gave his cloak a violent tug making his neck red.
AbuHurayrah said: The cloak was coarse. He turned to him and the Arabi said to him: Load these two camels of mine, for you do not give me anything from your property or from your father's property.
The Prophet (peace_be_upon_him) said to him: No, I ask Allah's forgiveness; no, I ask Allah's forgiveness; no, I ask Allah's forgiveness. I shall not give you the camel-load until you make amends for the way in which you tugged at me.
Each time the Arabi said to him: I swear by Allah, I shall not do so.
He then mentioned the rest of the tradition. He (the Prophet), then called a man and said to him: Load these two camels of his: one camel with barley and the other with dates. He then turned to us and said: Go on your way with the blessing of Allah.
