‘Umar reported God’s messenger as saying, “If four people give a good testimony about any Muslim, God will cause him to enter paradise.” ‘Umar said they asked whether this would apply if three testified, and he said it would. They further asked if it would apply if two testified, and he said it would; but they did not ask him about one. Bukhari transmitted it.
