"The Messenger of Allah (ﷺ) took a camel of a particular age on loan. He gave back to him a camel of a better age than the one he was given. He said: 'The best among you is the best in repaying.'"

He said: There is something on this topic from Abu Rafi'.

The Hadith of Abu Hurairah is a Hasan Sahih Hadith. Shu'bah and Sufyan reported it from Salamah.

This is acted upon according to some of the people of knowledge, they saw no harm is taking a camel of a particular age as a loan. This is the view of Ash-Shafi'i, Ahmad, and Ishaq. But some of them disliked that.
Jami` at-Tirmidhi Book 14, Hadith 119
← Previous Hadith That the Messenger of Allah (ﷺ) passed by a pile of food. He put his fingers in it and felt wetness. He said: 'O owner of the food! What is this ?' He replied: 'It was rained upon O Messenger of Allah.' He said: 'Why not put it on top of the food so the people can see it?' Then he said: 'Whoever cheats, he is not one of us.'"

He said: There are narrations on this topic from Ibn 'Umar, Abu Al-Hamra', Ibn 'Abbas, Buraidah, Abu Burdah bin Niyar, and Hudhaifah bin Al-Yaman.

The Hadith of Abu Hurairah is Hasan Sahih Hadith. This is acted upon according to the people of knowledge. They dislike cheating and they say that cheating is unlawful.

Jami` at-Tirmidhi Book 14, Hadith 118 Next Hadith → "A man behaved in a rude manner while trying to collect a debt from the Messenger of Allah (ﷺ). So his Companions were about to harm him. The Messenger of Allah (ﷺ) said: 'Leave him, for indeed the owner of the the right has the right to speak.' Then he said: 'Purchase a camel for him and give it to him.' So they searched out but they did not find a camel but of a better ager than his camel. So he said: 'Buy it and give it to him. For indeed the best of you is the best in repaying.'"
