4:15Those of your women who commit lewdness, you must have four witnesses against them, from among you. If they testify, confine them to the homes until death claims them, or God makes a way for them.

4:66Had We decreed for them: “Kill yourselves,” or “Leave your homes,” they would not have done it, except for a few of them. But had they done what they were instructed to do, it would have been better for them, and a firmer confirmation.
