Surat Al-Ahzaab (The Clans) - الأحزاب

وَإِذْ تَقُولُ لِلَّذِىٓ أَنْعَمَ ٱللَّهُ عَلَيْهِ وَأَنْعَمْتَ عَلَيْهِ أَمْسِكْ عَلَيْكَ زَوْجَكَ وَٱتَّقِ ٱللَّهَ وَتُخْفِى فِى نَفْسِكَ مَا ٱللَّهُ مُبْدِيهِ وَتَخْشَى ٱلنَّاسَ وَٱللَّهُ أَحَقُّ أَن تَخْشَىٰهُ فَلَمَّا قَضَىٰ زَيْدٌ مِّنْهَا وَطَرًا زَوَّجْنَٰكَهَا لِكَىْ لَا يَكُونَ عَلَى ٱلْمُؤْمِنِينَ حَرَجٌ فِىٓ أَزْوَٰجِ أَدْعِيَآئِهِمْ إِذَا قَضَوْا۟ مِنْهُنَّ وَطَرًا وَكَانَ أَمْرُ ٱللَّهِ مَفْعُولًا ﴿٣٧﴾ مَّا كَانَ عَلَى ٱلنَّبِىِّ مِنْ حَرَجٍ فِيمَا فَرَضَ ٱللَّهُ لَهُۥ سُنَّةَ ٱللَّهِ فِى ٱلَّذِينَ خَلَوْا۟ مِن قَبْلُ وَكَانَ أَمْرُ ٱللَّهِ قَدَرًا مَّقْدُورًا﴿٣٨﴾
