[Machine] In His saying (and their husbands have the better right to take them back in that period, if they wish for reconciliation) [Al-Baqarah 2:228], it is said that when a man divorces a pregnant woman once or twice, he has the better right to take her back as long as she has not given birth, and it is not permissible for her to conceal her pregnancy. And this is His saying (nor is it lawful for them to conceal what Allah has created in their wombs) [Al-Baqarah 2: 228].  

فِي قَوْلِهِ {وَبُعُولَتُهُنَّ أَحَقُّ بِرَدِّهِنَّ فِي ذَلِكَ إِنْ أَرَادُوا إِصْلَاحًا} [البقرة 228] قَالَ يَقُولُ إِذَا طَلَّقَ الرَّجُلُ الْمَرْأَةَ تَطْلِيقَةً أَوِ اثْنَتَيْنِ وَهِيَ حَامِلٌ فَهُوَ أَحَقُّ بِرَجْعَتِهَا مَا لَمْ تَضَعْ وَلَا يَحِلُّ لَهَا أَنْ تَكْتُمَ حَمْلَهَا وَهُوَ قَوْلُهُ {وَلَا يَحِلُّ لَهُنَّ أَنْ يَكْتُمْنَ مَا خَلَقَ اللهُ فِي أَرْحَامِهِنَّ} [البقرة 228]
