Surah Al-Baqarah, verse 228

وَٱلْمُطَلَّقَـٰتُ يَتَرَبَّصْنَ بِأَنفُسِهِنَّ ثَلَـٰثَةَ قُرُوٓءٍ ۚ وَلَا يَحِلُّ لَهُنَّ أَن يَكْتُمْنَ مَا خَلَقَ ٱللَّهُ فِىٓ أَرْحَامِهِنَّ إِن كُنَّ يُؤْمِنَّ بِٱللَّهِ وَٱلْيَوْمِ ٱلْـَٔاخِرِ ۚ وَبُعُولَتُهُنَّ أَحَقُّ بِرَدِّهِنَّ فِى ذَٰلِكَ إِنْ أَرَادُوٓا۟ إِصْلَـٰحًا ۚ وَلَهُنَّ مِثْلُ ٱلَّذِى عَلَيْهِنَّ بِٱلْمَعْرُوفِ ۚ وَلِلرِّجَالِ عَلَيْهِنَّ دَرَجَةٌ ۗ وَٱللَّهُ عَزِيزٌ حَكِيمٌ ﴿٢٢٨﴾

2:228 Divorced women should wait for three menstrual cycles. It is not permissible for them to hide what Allah has created in their wombs, if they believe in Allah and the Last Day. Their husbands have the greater right to take them back within that period, if they want reconciliation. Women have rights similar to the rights over them in a reasonable manner, although men have a higher degree [of responsibility] over them. And Allah is All-Mighty, All-Wise
