Arabic

حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ الرَّحِيمِ، حَدَّثَنَا مُعَلَّى بْنُ مَنْصُورٍ، عَنْ حَمَّادِ بْنِ زَيْدٍ، حَدَّثَنَا ثَابِتٌ، عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه ـ أَنَّ هَذِهِ، الآيَةَ ‏{‏وَتُخْفِي فِي نَفْسِكَ مَا اللَّهُ مُبْدِيهِ‏}‏ نَزَلَتْ فِي شَأْنِ زَيْنَبَ ابْنَةِ جَحْشٍ وَزَيْدِ بْنِ حَارِثَةَ‏.‏
