وَإِذْ أَسَرَّ ٱلنَّبِىُّ إِلَىٰ بَعْضِ أَزْوَٰجِهِۦ حَدِيثًا فَلَمَّا نَبَّأَتْ بِهِۦ وَأَظْهَرَهُ ٱللَّهُ عَلَيْهِ عَرَّفَ بَعْضَهُۥ وَأَعْرَضَ عَنۢ بَعْضٍ فَلَمَّا نَبَّأَهَا بِهِۦ قَالَتْ مَنْ أَنۢبَأَكَ هَٰذَا قَالَ نَبَّأَنِىَ ٱلْعَلِيمُ ٱلْخَبِيرُ ﴿٣﴾

And (remember) when the Prophet (SAW) disclosed a matter in confidence to one of his wives (Hafsah), so when she told it (to another i.e. 'Aishah), and Allah made it known to him, he informed part thereof and left a part. Then when he told her (Hafsah) thereof, she said: "Who told you this?" He said: "The All-Knower, the All-Aware (Allah) has told me". The Noble Quran
