Hadith.5094 - Imam Jafar ibn Muhammad Al-Sadiq (as) said: "Indeed, the angels withdraw from gatherings where gambling occurs and curse the one involved in it, except in the case of betting on hoofed animals, animals with padded feet, feathered birds, and arrows. And the Messenger of Allah (swt) (peace be upon him and his family) himself raced with Usamah ibn Zayd and conducted horse races."
