﴿ وَيَدْرَؤُا۟ عَنْهَا ٱلْعَذَابَ أَن تَشْهَدَ أَرْبَعَ شَهَٰدَٰتٍۭ بِٱللَّهِ ۙ إِنَّهُۥ لَمِنَ ٱلْكَٰذِبِينَ ﴾

“But [as for the wife, all] chastisement shall be averted from her by her calling God four times to witness that he is indeed telling a lie,”

(And it shall avert) the judge will abstain from applying (the punishment from her) the punishment of stoning on the accused wife (if she bear witness before Allah four times) if the woman swears four times by Allah with Whom there is no other god (that the thing he) her husband (saith is indeed false) is untrue,
