There are forty good qualities, the best of which is the lending of a milch goat. Anyone carries out any of these virtuous deeds seeking its reward (from Allah) with firm confidence that he will receive it, Allah will admit him to Paradise

Explanation

The Prophet (may Allah's peace and blessings be upon him) encourages his Ummah to do goodness that involves, as he mentioned, forty good qualities. He mentioned only one quality, which is the best of them, and kept the rest unknown. This quality is the case when a sheep owner lends a poor person a milch goat to benefit from its milk and return it after meeting his/her need to its owner. This Hadīth indicates that righteous deeds are easy and numerous, and thus people should compete in doing them.
