Quran 24:3 — Light (Al-Noor)

The adulterer will end up marrying an adulteress or an idol worshiper, and the adulteress will end up marrying an adulterer or an idol worshiper. This is prohibited for the believers.

[24:2] The adulteress and the adulterer you shall whip each of them a hundred lashes. Do not be swayed by pity from carrying out GOD's law, if you truly believe in GOD and the Last Day. And let a group of believers witness their penalty.*

[24:4] Those who accuse married women of adultery, then fail to produce four witnesses, you shall whip them eighty lashes, and do not accept any testimony from them; they are wicked.
