The Book of Miscellany
Anas (May Allah be pleased with him) reported:
I was walking with Messenger of Allah (ﷺ) who was wearing a Najrani cloak with a very thick border when a bedouin happened to meet him. He took hold of the side of his cloak and drew it violently. I noticed that the violence of jerk had bruised the neck of Messenger of Allah (ﷺ). The bedouin said: "O Muhammad! Give me out of Allah's wealth that you possess." Messenger of Allah (ﷺ) turned to him and smiled and directed that he should be given something.

[Al-Bukhari and Muslim].

وعن أنس رضي الله عنه قال‏:‏ كنت أمشى مع رسول الله صلى الله عليه وسلم، وعليه برد نجرانى غليظ الحاشية، فأدركه أعرابى، فجبذه بردائه جبذة شديدة، فنظرت إلى صفحة عاتق النبى صلى الله عليه وسلم، وقد أثرت بها حاشية البرد من شدة فضحك، ثم قال‏:‏ يا محمد مر لى من مال الله الذى عندك، فالتفت إليه فضحك ثم أمر له بعطاء‏.‏ ‏(‏‏(‏متفق عليه‏)‏‏)‏
