Verse 3

وَٱلَّذِينَ يُظَـٰهِرُونَ مِن نِّسَآئِهِمْ ثُمَّ يَعُودُونَ لِمَا قَالُوا۟ فَتَحْرِيرُ رَقَبَةٍ مِّن قَبْلِ أَن يَتَمَآسَّا ذَٰلِكُمْ تُوعَظُونَ بِهِۦ وَٱللَّهُ بِمَا تَعْمَلُونَ خَبِيرٌ

As for those who estrange their wives by declaring them as their mothers, then wish to reconcile, they shall free a slave, before they resume their husband-wife relationship. You are thus being enlightened. And God is All Cognizant of everything you do.
