I asked Abu Abdullah (as), about the testimony of one who plays with pigeons. Imam (as) said: "There is no harm if he is not known for sinfulness." I said: The people around us say that Umar called them to be a 'devil'. Imam (as) replied: "Glory be to Allah (swt)! Do you not know that the Messenger of Allah (swt), peace and blessings be upon him and his family, said: 'Indeed, the angels flee from gambling and curse its participant, except for activities involving hoofs, claws, feathers, and arrows, for the angels attend such activities.' And the Messenger of Allah (swt), peace and blessings be upon him and his family, raced with Usamah ibn Zayd and ran horses."
