Abu Rafi' reported that Allah's Messenger (ﷺ) took from a man as a loan a young camel (below six years). Then the camels of Sadaqa were brought to him. He ordered Abu Rafi' to return to that person the young camel (as a return of the loan). Abu Rafi' returned to him and said:I did not find among them but better camels above the age of six. He (the Holy Prophet) said: Give that to him for the best men are those who are best in paying off the debt

Abu Rafi', the freed slave of Allah's Messenger (ﷺ), said:Allah's Messenger (ﷺ) took as a loan (the rest of the hadith is the same), but with this variation that he (the Holy Prophet) said: Good amongst the servants of Allah is he who is best in paying off the debt
