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?”

2:42And do not mix truth with falsehood, and do not conceal the truth while you know.

2:76And when they come across those who believe, they say, “We believe,” but when they come together privately, they say, “Will you inform them of what God has disclosed to you, so that they might dispute with you concerning it before your Lord?” Do you not understand?

2:77Do they not know that God knows what they conceal and what they reveal?

2:140Or do you say that Abraham, Ishmael, Isaac, Jacob, and the Patriarchs were Jews or Christians? Say, “Do you know better, or God?” And who does greater wrong than he who conceals a testimony he has from God? God is not unaware of what you do.

2:142The ignorant among the people will say, “What has turned them away from the direction of prayer they once followed?” Say, “To God belong the East and the West. He guides whom He wills to a straight path.”

2:143Thus We made you a moderate community, that you may be witnesses to humanity, and that the Messenger may be a witness to you. We only established the direction of prayer, which you once followed, that We may distinguish those who follow the Messenger from those who turn on their heels. It is indeed difficult, except for those whom God has guided. But God would never let your faith go to waste. God is Kind towards the people, Merciful.

2:178O you who believe! Retaliation for the murdered is ordained upon you: the free for the free, the slave for the slave, the female for the female. But if he is forgiven by his kin, then grant any reasonable demand, and pay with good will. This is a concession from your Lord, and a mercy. But whoever commits aggression after that, a painful torment awaits him.

2:222And they ask you about menstruation: say, “It is harmful, so keep away from women during menstruation. And do not approach them until they have become pure. Once they have become pure, approach them in the way God has directed you.” God loves the repentant, and He loves those who keep clean.”

2:228Divorced women shall wait by themselves for three periods. And it is not lawful for them to conceal what God has created in their wombs, if they believe in God and the Last Day. Meanwhile, their husbands have the better right to take them back, if they desire reconciliation. And women have rights similar to their obligations, according to what is fair. But men have a degree over them. God is Mighty and Wise.

2:283If you are on a journey, and cannot find a scribe, then a security deposit should be handed over. But if you trust one another, let the trustee fulfill his trust, and let him fear God, his Lord. And do not conceal testimony. Whoever conceals it is sinner at heart. God is aware of what you do.

2:284To God belongs everything in the heavens and the earth. Whether you reveal what is within your selves, or conceal it, God will call you to account for it. He forgives whom He wills, and He punishes whom He wills. God is Able to do all things.
