It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) passed by a man who was milking a goat, and he (peace and blessings be upon him) said: "O so-and-so! When you milk, leave something for its young, for it is among the most kind of animals (towards its offspring)."
This hadith is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) only with this chain.
