Sahih Muslim Hadith 7512

I and my father set out in search of knowledge to a tribe of the Ansar before their death (i.e. before the Companions of the Prophet left the world) and I was the first to meet Abu Yasar رضی اللہ عنہ, a Companion of Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) and there was a young man with him who carried the record of letters with him and there was a mantle prepared by the tribe of Ma'afiri upon him. And his servant too had a Ma'afiri mantle over him. My father said to him: My uncle, I see the signs of anger or that of agony on your face. He said: Yes, such and such person, the son of so and so, of the tribe of Harami owed me a debt. I went to his family, extended salutations and said: Where is he? They said: He is not here. Then came out to me his son who was at the threshold of his youth. I said to him: Where is your father? He said: No sooner did he hear your sound than he hid himself behind my mother's bedstead. I said to him: Walk out to me, for I know where you are. He came out. I said to him: What prompted you to hide yourself from me? He said: By God, whatever I would say to you would not be a lie. By Allah, I fear that I should tell a lie to you and in case of making promise with you I should break it, as you are the Companion of Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ). The fact is that I was hard up in regard to money. I said: Do you adjure by Allah? He said: I adjure by Allah. I said: Do you adjure by Allah? He said: I adjure by Allah. I said: Do you adjure by Allah? He said: I adjure by Allah. Then he brought his promissory note and he wrote off (the debt) with his hand and said: Make payment when you find yourself solvent enough to pay me back; if you are not, then there is no liability upon you. These two eyes of mine saw, and he (Abu'I-Yasar) placed his fingers upon his eyes and these two ears of mine heard and my heart retained, and he pointed towards his heart that Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) said: He who gives time to one who is financially hard up (in the payment of debt) or writes off his debt, Allah will provide him His shadow.
