And (as for) those of you who die and leave wives behind, they should keep themselves in waiting for four months and ten days; then when they have fully attained their term, there is no blame on you for what they do for themselves in a lawful manner; and Allah is aware of what you do.

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.
