Mishkat al-Masabih 4880 — Manners

Abdullah ibn Abu Al-Hasma Narrated from:

I had bought something from the Prophet صلى الله عليه وسلم before he was made a prophet. Part of the payment remained to be paid by me and I promise him that I would bring it to him at his (that very) place, but I forgot (my promise). Three days later, I remember it and I went to that place to find him there. He said, 'you have put me to much trouble. I have been waiting here for you since three days. [3]
