Surah An-Nur, ayah 8

وَيَدۡرَؤُاْ عَنۡهَا ٱلۡعَذَابَ أَن تَشۡهَدَ أَرۡبَعَ شَهَٰدَٰتِۭ بِٱللَّهِ إِنَّهُۥ لَمِنَ ٱلۡكَٰذِبِينَ ٨

Wayadra'u 'anhal-'adhāba an tashhada arba'a shahādāti billāhi innahū laminal-kādhibīn

But it will prevent punishment from her if she gives four testimonies [swearing] by Allāh that indeed, he is of the liars.
