Surat At-Tahrim (The Prohibition) - التحريم

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 when the prophet secretly communicated a piece of information to one of his wives-- but when she informed (others) of it, and Allah made him to know it, he made known part of it and avoided part; so when he informed her of it, she said: Who informed you of this? He said: The Knowing, the one Aware, informed me.
