WAITING IN A PLACE FOR THREE DAYS TO KEEP ONE’S WORD
Narrated Hazrat Abdullah ibn Abul Hamsa’ (radhiyallahu anhu):
I bought something from the Prophet (sallallahu alayhi wasallam) before he received his Prophetic commission, and as there was something still due to him I promised him that I would bring it to him at his place, but I forgot. When I remembered three days later, I went to that place and found him there.
He said: “You have inconvenienced me, young man. I have been here for three days waiting for you.”
(Sunan Abu Dawud)
