ٱلزَّانِي لَا يَنكِحُ إِلَّا زَانِيَةً أَوۡ مُشۡرِكَةٗ وَٱلزَّانِيَةُ لَا يَنكِحُهَآ إِلَّا زَانٍ أَوۡ مُشۡرِكٞۚ وَحُرِّمَ ذَٰلِكَ عَلَى ٱلۡمُؤۡمِنِينَ

Azzaanee laa yankihu illaa zaaniyatan aw mushrikatanw wazzaaniyatu laa yankihuhaaa illaa zaanin aw mushrik; wa hurrima zaalika 'alal mu'mineen

Let no man guilty of adultery or fornication marry and but a woman similarly guilty, or an Unbeliever: nor let any but such a man or an Unbeliever marry such a woman: to the Believers such a thing is forbidden.

— An-Nur (ٱلنُّور), 24:3
