At-Tahrim 66:3

And [remember] when the Prophet told one of his wives something in secret. Then when she disclosed it [to another wife], and Allah made it known to him, he told [the disclosing wife] part of what was disclosed and overlooked a part. When he informed her of that, she said, “Who informed you of this?” He said, “I was informed by the All-Knowing, the All-Aware.

And [remember] when the Prophet confided to one of his wives a statement; and when she informed [another] of it and Allāh showed it to him, he made known part of it and ignored a part. And when he informed her about it, she said, "Who told you this?" He said, "I was informed by the Knowing, the Aware."

3. And (remember) when the Prophet (صلى الله عليه وسلم) disclosed a matter in confidence to one of his wives (Hafsah), then she told it (to another i.e. ‘Âishah). And Allâh 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 (Allâh) has told me."

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.
