سورة At-Tahrim ( The Prohibition ) - الآية 3

The Prophet confided something to one of his wives and then she disclosed it (to another); so after Allah revealed to the Prophet (that she had disclosed that secret), he made a part of it known to her and passed over a part of it. And when he told her about this (i.e., that she had disclosed the secret entrusted to her), she asked: “Who informed you of this?” He said: “I was told of it by He Who is All-Knowing, All-Aware.”
