Sunan Ibn Majah, Chapter: The Chapters on Ascetism (Zuhd)

"The Messenger of Allah (saw) sent me to a man whom he was talking to lend him a she-camel (for milking) and to be returned, but he refused. Then he sent me to another man, who sent a she-camel to him. When the Messenger of Allah (saw) saw it, he said: O Allah, bless it and bless the one who sent it." Nuqadah said: "I said to the Messenger of Allah (saw): And for the one who brought it. He said: And (bless) the one who brought it. Then he ordered that it should be milked and it yielded plenty of milk. The Messenger of Allah (saw) said: O Allah, increase the wealth of so-and-so, meaning the first one who did not give a camel; and give so-and-so provision day by day, meaning the one who had sent the she-camel."
