Ameer al-Momineen (a.s) said: “There are six groups of people who do not deserve to be greeted, and there are six acts which are those that the people of Lot did. Those who do not deserve to be greeted are: Jews, Christians, chess players, dice players; people of alcohol (alcoholics), Barbat and Tanbour, those who joke around by swearing at each other's mother, and poets. The following are things that the people of Lot did: shooting round bullets using a kind of sling; chewing gum; leaving their shirt's unbuttoned (so that their chest is seen).”
