Sahih Muslim, 177 b
sahih

Dawud reported on the same authorities the hadith as narrated above by Ibn 'Uliyya and added:

She ('A'isha) said: If Muhammad were to conceal anything which was sent to him, he would have certainly concealed this verse:" And when you saidst to him on whom Allah had conferred favour and you too had conferred favour: Keep your wife to thyself and fear Allah, and you wast concealing in your heart that which Allah was going to disclose, and you wast fearing men while Allah has a better right that you shouldst fear Him."

وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا عَبْدُ الْوَهَّابِ، حَدَّثَنَا دَاوُدُ، بِهَذَا الإِسْنَادِ نَحْوَ حَدِيثِ ابْنِ عُلَيَّةَ وَزَادَ قَالَتْ وَلَوْ كَانَ مُحَمَّدٌ صلى الله عليه وسلم كَاتِمًا شَيْئًا مِمَّا أُنْزِلَ عَلَيْهِ لَكَتَمَ هَذِهِ الآيَةَ ‏{‏ وَإِذْ تَقُولُ لِلَّذِي أَنْعَمَ اللَّهُ عَلَيْهِ وَأَنْعَمْتَ عَلَيْهِ أَمْسِكْ عَلَيْكَ زَوْجَكَ وَاتَّقِ اللَّهَ وَتُخْفِي فِي نَفْسِكَ مَا اللَّهُ مُبْدِيهِ وَتَخْشَى النَّاسَ وَاللَّهُ أَحَقُّ أَنْ تَخْشَاهُ‏}‏
