Narrated 'Aishah [may Allah be pleased with her]: "If the Prophet was to have hidden anything from the Revelation, then he would have hidden this Ayah: 'When you said to him on whom Allah has bestowed grace and you have done a favor (33:37).'"
حَدَّثَنَا مُحَمَّدُ بْنُ أَبَانَ، حَدَّثَنَا ابْنُ أَبِي عَدِيٍّ، عَنْ دَاوُدَ بْنِ أَبِي هِنْدٍ، عَنِ الشَّعْبِيِّ، عَنْ مَسْرُوقٍ، عَنْ عَائِشَةَ، رضى الله عنها قَالَتْ لَوْ كَانَ النَّبِيُّ صلى الله عليه وسلم كَاتِمًا شَيْئًا مِنَ الْوَحْىِ لَكَتَمَ هَذِهِ الآيَةَِ : ( إذْ تَقُولُ لِلَّذِي أَنْعَمَ اللَّهُ عَلَيْهِ وَأَنْعَمْتَ عَلَيْهِ ) الآيَةَ . قَالَ هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
