Anas narrates,
I was walking with the Messenger of Allah, may Allah bless him and grant him peace, and he was wearing a Najrani cloak with a thick border. A bedouin came up to him and pulled the cloak violently. I looked at the Prophet's shoulder and it had been marked by the border of the cloak due to the severity of his pull. Then he said:
'Muhammad, allot to me some of property of Allah which you have.'
He turned to him and laughed and then ordered a gift to be given to him.
