Regarding His statement: “...and if the one who Allah had blessed says…” (Aḥzāb 33:37) he said, "He was favored by Allah with Islam, and the Prophet ﷺ favored him with freedom ˹from slavery˺."

˹Regarding˺ “and hold on to your wife” (Aḥzāb 33:37), Qatādah said, Zayd came to Messenger of Allah ﷺ then said, "Zaynab is is stern toward me with her tongue and I want to divorce her." Then the Prophet ﷺ said, "Fear Allāh and hold on to your wife," while the Prophet ﷺ would have liked that he would divorce her, however, he feared what people would say if he ordered him to divorce her. Then Allah revealed “...and you hide within yourself what Allah is making known and you fear the people while Allah is more deserving to be feared. And when Zayd had fulfilled his desire with her...” (Aḥzāb 33:37).

He said, when he had divorced her, i.e. "We married you to her." (Aḥzāb 33:37)  

فِي قَوْلِهِ {وَإِذْ تَقُولُ لِلَّذِي أَنْعَمَ اللهُ عَلَيْهِ وَأَنْعَمْتَ عَلَيْهِ} قَالَ «أَنْعَمَ اللهُ عَلَيْهِ بِالْإِسْلَامِ وَأَنْعَمَ عَلَيْهِ النَّبِيُّ ﷺ بِالْعِتْقِ»

{أَمْسَكْ عَلَيْكَ زَوْجَكَ} قَالَ قَتَادَةُ جَاءَ زَيْدٌ إِلَى النَّبِيِّ ﷺ فَقَالَ إِنَّ زَيْنَبَ اشْتَدَّ عَلِيَّ لِسَانُهَا وَإِنِّي أُرِيدُ أَنْ أُطَلِّقُهَا فَقَالَ النَّبِيُّ ﷺ «اتَّقِ اللهَ وَأَمْسَكْ عَلَيْكَ زَوْجَكَ» وَالنَّبِيُّ ﷺ يُحِبُّ أَنْ يُطَلِّقَهَا وَخَشِيَ قَالَةَ النَّاسِ إِنْ أَمَرَهُ بِطَلَاقِهَا فَأَنْزَلَ {وَتُخْفِي فِي نَفْسِكَ مَا اللهُ مُبْدِيهِ وَتَخْشَى النَّاسَ وَاللهُ أَحَقُّ أَنْ تَخْشَاهُ فَلَمَّا قَضَى زَيْدٌ مِنْهَا وَطَرًا}

قَالَ لَمَّا طَلَّقَهَا زَيْدٌ {زَوَّجْنَاكَهَا}
