O you who have believed, indeed, among your wives and your children are enemies to you, so beware of them. But if you pardon and overlook and forgive - then indeed, Allah is Forgiving and Merciful.  

يَا أَيُّهَا الَّذِينَ آمَنُوا إِنَّ مِنْ أَزْوَاجِكُمْ وَأَوْلَادِكُمْ عَدُوًّا لَكُمْ فَاحْذَرُوهُمْ ۚ وَإِنْ تَعْفُوا وَتَصْفَحُوا وَتَغْفِرُوا فَإِنَّ اللَّهَ غَفُورٌ رَحِيمٌ  

Ibn Abbas was asked by a man about this Ayah: O you who believe! Verity, among your wives and your children there are enemies for you; therefore beware of them! He said: “These are men who submitted (to Islam) in Makkah, and they wanted to come to the Prophet but their wives and children refused to allow them to come to the Messenger of Allah. So when they came to the Messenger of Allah, they saw that the people had gained such understanding in the religion that they wanted to punish them (their families). So Allah revealed the Ayah: O you who believe! Verily, among your wives and your children there are enemies for you; therefore beware of them!”  

عَنْ هَذِهِ الآيَةِ ( يا أَيُّهَا الَّذِينَ آمَنُوا إِنَّ مِنْ أَزْوَاجِكُمْ وَأَوْلاَدِكُمْ عَدُوًّا لَكُمْ فَاحْذَرُوهُمْ ) قَالَ هَؤُلاَءِ رِجَالٌ أَسْلَمُوا مِنْ أَهْلِ مَكَّةَ وَأَرَادُوا أَنْ يَأْتُوا النَّبِيَّ ﷺ فَأَبَى أَزْوَاجُهُمْ وَأَوْلاَدُهُمْ أَنْ يَدَعُوهُمْ أَنْ يَأْتُوا رَسُولَ اللَّهِ ﷺ فَلَمَّا أَتَوْا رَسُولَ اللَّهِ ﷺ رَأَوُا النَّاسَ قَدْ فَقِهُوا فِي الدِّينِ هَمُّوا أَنْ يُعَاقِبُوهُمْ فَأَنْزَلَ اللَّهُ ﷻ َّ ( يا أَيُّهَا الَّذِينَ آمَنُوا إِنَّ مِنْ أَزْوَاجِكُمْ وَأَوْلاَدِكُمْ عَدُوًّا لَكُمْ فَاحْذَرُوهُمْ ) الآيَةَ  

[Machine] This verse {Indeed, among your wives and your children are enemies to you, so beware of them} [Al-Taghabun 14] was revealed in a group of people from the people of Mecca who embraced Islam and wanted to come to the Prophet ﷺ . However, their wives and children refused to let them go, so they came to Medina. When they arrived in the presence of the Messenger of Allah ﷺ , they saw that they had attained knowledge, so they understood that they deserve punishment. Then Allah, the Almighty, revealed the verse {But if you pardon and overlook} [Al-Taghabun 14].  

نَزَلَتْ هَذِهِ الْآيَةُ {إِنَّ مِنْ أَزْوَاجِكُمْ وَأَوْلَادِكُمْ عَدُوًّا لَكُمْ فَاحْذَرُوهُمْ} [التغابن 14] فِي قَوْمٍ مِنْ أَهْلِ مَكَّةَ أَسْلَمُوا وَأَرَادُوا أَنْ يَأْتُوا النَّبِيَّ ﷺ فَأَبَى أَزْوَاجُهُمْ وَأَوْلَادُهُمْ أَنْ يَدْعُوهُمْ فَأَتَوْا الْمَدِينَةَ فَلَمَّا قَدِمُوا عَلَى رَسُولِ اللَّهِ ﷺ رَأَوْهُمْ قَدْ فَقِهُوا فَهَمُّوا أَنْ يُعَاقِبُوهُمْ فَأَنْزَلَ اللَّهُ ﷻ {وَإِنْ تَعْفُوا وَتَصْفَحُوا} [التغابن 14] الْآيَةَ
