At- Tahrim - 66:3

وَإِذْ أَسَرَّ النَّبِيُّ إِلَى بَعْضِ أَزْوَاجِهِ حَدِيثًا فَلَمَّا نَبَّأَتْ بِهِ وَأَظْهَرَهُ اللَّهُ عَلَيْهِ عَرَّفَ بَعْضَهُ وَأَعْرَضَ عَن بَعْضٍ فَلَمَّا نَبَّأَهَا بِهِ قَالَتْ مَنْ أَنبَأَكَ هَذَا قَالَ نَبَّأَنِيَ الْعَلِيمُ الْخَبِيرُ
[66:3]
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.
When the Prophet disclosed a matter in confidence to one of his consorts, and she then divulged it (to another), and Allah made it known to him, he confirmed part thereof and repudiated a part. Then when he told her thereof, she said, "Who told thee this? "He said, "He told me Who knows and is well-acquainted (with all things)."
When the Prophet confided a fact unto one of his wives and when she afterward divulged it and Allah apprised him thereof, he made known (to her) part thereof and passed over part. And when he told it her she said: Who hath told thee? He said: The Knower, the Aware hath told me.
