It was narrated from Abu Rafi’ that the Messenger of Allah صلی اللہ علیہ وآلہ وسلم , borrowed a young camel from a man, then he came to get his camel back. He said to a man: “Go and buy a young camel for him.” He came and said: “I could only get a Raba‘i camel of good quality.” He said: “Give it to him, for the best of the Muslims is the one who is best in repaying.” (Sahih)
