Holy Qur’an 66:4

And when the Prophet confided a matter unto one of his wives and she then divulged it, and Allah informed him of it, he made known to her part thereof, and avoided mentioning part of it. And when he informed her of it, she said, ‘Who has informed thee of it?’ He said, ‘The All-Knowing, the All-Aware God has informed me.’
