2:33He said, “O Adam, tell them their names.” And when he told them their names, He said, “Did I not tell you that I know the secrets of the heavens and the earth, and that I know what you reveal and what you conceal?”

2:235You commit no error by announcing your engagement to women, or by keeping it to yourselves. God knows that you will be thinking about them. But do not meet them secretly, unless you have something proper to say. And do not confirm the marriage tie until the writing is fulfilled. And know that God knows what is in your souls, so beware of Him. And know that God is Forgiving and Forbearing.

2:271If you give charity openly, that is good. But if you keep it secret, and give it to the needy in private, that is better for you. It will atone for some of your misdeeds. God is cognizant of what you do.
