It was narrated from Abu Rafi' that:
the Prophet (ﷺ) asked a man to give as a loan a young camel and said: “When the camels of the Sadaqah come, we will pay you back.” When the camels came, he said: " O Abu Rafi', pay this man back for his Young camel." But all I could find was a seven-year-old camel or that which is better. I told the Prophet (ﷺ) and he said: "Give it to him, for the best of People are those who are best in repaying."
