Mukhtasar Muslim (Abridged) 1013 — Whoever swears by Lat and Uzza

Abu Huraira (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings of Allah be upon him) said: If any of you swears by saying, "By Lat!", he should say, "There is no god but Allah." And whoever says to another, "Come, let us gamble," he should give charity. In one narration, along with "Lat," "Uzza" is also mentioned.
