Sayyiduna Ibn Abbas (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) said: "Accept the counsel to treat goats well, for they are gentle livestock, and they are also in Paradise. The most beloved livestock to Allah are sheep. Hold fast to white, for Allah created Paradise white; so let your living wear it, and shroud your dead in it. And the blood of a white sheep is greater with Allah than the blood of two black ones."
