أَخْبَرَنَا سُوَيْدُ بْنُ نَصْرٍ، قَالَ أَنْبَأَنَا عَبْدُ اللَّهِ، قَالَ حَدَّثَنَا سُلَيْمَانُ بْنُ الْمُغِيرَةِ، عَنْ ثَابِتٍ، عَنْ أَنَسٍ، قَالَ لَمَّا انْقَضَتْ عِدَّةُ زَيْنَبَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم لِزَيْدٍ ‏
"‏ اذْكُرْهَا عَلَىَّ ‏"‏ ‏.‏ قَالَ زَيْدٌ فَانْطَلَقْتُ فَقُلْتُ يَا زَيْنَبُ أَبْشِرِي أَرْسَلَنِي إِلَيْكِ رَسُولُ اللَّهِ صلى الله عليه وسلم يَذْكُرُكِ ‏.‏ فَقَالَتْ مَا أَنَا بِصَانِعَةٍ شَيْئًا حَتَّى أَسْتَأْمِرَ رَبِّي فَقَامَتْ إِلَى مَسْجِدِهَا وَنَزَلَ الْقُرْآنُ وَجَاءَ رَسُولُ اللَّهِ صلى الله عليه وسلم فَدَخَلَ بِغَيْرِ أَمْرٍ ‏.‏

It was narrated that Anas said: "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."
