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."

And (remember) when the Prophet told one of his wives something in secret. So, when she disclosed it (to another wife), and Allah made it known to him, he told (the disclosing wife) part of it,and avoided another part. So when he informed her about it, she said, “Who told you about this?” He said, “I was told of it by the All-Knowing, the All-Aware.
