Musnad Ahmad

It is narrated from Hazrat Naqadah Asadi that the Prophet (peace be upon him) sent him to a man to get a she-camel, but that person refused to give the she-camel. Then he sent him to another man, and that man sent the she-camel to the service of the Prophet (peace be upon him). When the Prophet (peace be upon him) saw that Naqadah had brought the she-camel, he said, "O Allah, grant blessing in this she-camel and to the one who sent it." Naqadah submitted, "O Messenger of Allah, please also pray for the one who brought it." The Prophet (peace be upon him) said, "And grant blessing to the one who brought it as well." Then, on the order of the Prophet (peace be upon him), it was milked, and it gave plenty of milk. The Prophet (peace be upon him), praying for the first man who had refused to give the she-camel, said, "O Allah, increase so-and-so's wealth and children." And for the second man who had sent the she-camel, he said, "O Allah, grant him sustenance daily and gradually."
