"I brought a Jadha' sheep to Al-Madinah (for sale) but it remained with me. I saw Abu Hurairah and I asked him about it, so he said: 'I heard the Messenger of Allah (ﷺ) saying: "The best male" - or - "female Udhiyah is that from the Jadha' sheep." He said: "So the people took note of that (they became interested in buying)."
