Sahih Muslim | Book 15 | Hadith Number 4041

Narrated by Abu Huraira
Abu Huraira reported Allah's Messenger (may peace be upon him) as saying: He who takes an oath in the course of which he says: By Lat (and al-'Uzza), he should say: There is no god but Allah; and that it anyone says to his friend: "Come and I will gamble with you," he should pay sadaqa.
