Sahih Muslim 177bBook 1, Hadith 345
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}
She ('A'isha) said: If Muhammad were to conceal anything which was sent to him, he would have certainly concealed this verse:" And when thou saidst to him on whom Allah had conferred favour and thou too had conferred favour: Keep thy wife to thyself and fear Allah, and thou wast concealing in thy heart that which Allah was going to disclose, and thou wast fearing men while Allah has a better right that thou shouldst fear Him."
