Sa'eed bin Hani' said:
"I heard 'Irbad bin Sariyah say: 'I was with the Prophet (ﷺ) and a Bedouin said: "Pay me back for my young camel, and he gave him an older (i.e., better) camel." He said: 'O Messenger of Allah! It is older (i.e., better) than my camel.' The Messenger of Allah (ﷺ) said: 'The best of people are those who are best in repaying."'
