قَالَ مُصَنِّفُ هَذَا الْكِتَابِ رَحِمَهُ اللَّهُ يَعْنِي فِي الظِّهَارِ الَّذِي يَكُونُ بِشَرْطٍ فَأَمَّا الظِّهَارُ الَّذِي لَيْسَ بِشَرْطٍ فَمَتَى جَامَعَ صَاحِبَهُ مِنْ قَبْلِ أَنْ يُكَفِّرَ لَزِمَتْهُ كَفَّارَةٌ أُخْرَى كَمَا ذَكَرْتُهُ وَ مَتَى طَلَّقَ الْمُظَاهِرُ امْرَأَتَهُ سَقَطَتْ عَنْهُ الْكَفَّارَةُ فَإِذَا رَاجَعَهَا لَزِمَتْهُ فَإِنْ تَرَكَهَا حَتَّى يَحِلَّ أَجَلُهَا وَ تَزَوَّجَهَا رَجُلٌ آخَرُ وَ طَلَّقَهَا أَوْ مَاتَ عَنْهَا ثُمَّ تَزَوَّجَهَا وَ دَخَلَ بِهَا لَمْ تَلْزَمْهُ الْكَفَّارَةُ وَ يُجْزِي فِي كَفَّارَةِ الظِّهَارِ صَبِيٌّ مِمَّنْ وُلِدَ فِي الْإِسْلَامِ.
The author of this book, may Allah سبحانه وتعالى have mercy on him, explained that this ruling applies to ẓihar that is conditional. However, in the case of ẓihar that is unconditional, if the man engages in intercourse with his wife before offering expiation, an additional expiation becomes obligatory upon him, as previously mentioned. If a man who has performed ẓihar divorces his wife, the obligation of expiation is lifted. However, if he takes her back, the expiation becomes obligatory upon him again. But if he leaves her until her waiting period (iddah) ends and she marries another man who then divorces her or dies, and the first husband remarries her and consummates the marriage, the expiation is no longer required. Additionally, a child born into Islam is sufficient for fulfilling the expiation of ẓihar (in the case where freeing a slave is the expiation).
