"When the 'Iddah of Zainab was over, the Messenger of Allah said to Zaid: 'Propose marriage to her on my behalf.' Zaid went and said: 'O Zainab, rejoice, for the Messenger of Allah has sent me to you to propose marriage on his behalf.' She said: 'I will not do anything until I consult my Lord.' She went to her prayer place and Qur'an was revealed, then the Messenger of Allah came and entered upon her without any formalities." (Using translation from Nasāʾī 3251)
قَالَ رَسُولُ اللهِ ﷺ لِزَيْدٍ «اذْكُرْهَا عَلَيَّ» قَالَ زَيْدٌ فَانْطَلَقْتُ فَقُلْتُ يَا زَيْنَبُ أَبْشِرِي أَرْسَلَنِي إِلَيْكِ رَسُولُ اللهِ ﷺ يَذْكُرُكِ فَقَالَتْ مَا أَنَا بِصَانِعَةٍ شَيْئًا حَتَّى أَسْتَأْمِرَ رَبِّي فَقَامَتْ إِلَى مَسْجِدِهَا وَنَزَلَ الْقُرْآنُ «وَجَاءَ رَسُولُ اللهِ ﷺ حَتَّى دَخَلَ عَلَيْهَا فَدَخَلَ بِغَيْرِ أَمْرٍ»
