5:52You will see those in whose hearts is sickness racing towards them. They say, “We fear the wheel of fate may turn against us.” But perhaps God will bring about victory, or some event of His making; thereupon they will regret what they concealed within themselves.

5:99The Messenger’s sole duty is to convey. God knows what you reveal and what you conceal.

5:106O you who believe! When death approaches one of you, let two reliable persons from among you act as witnesses to the making of a bequest, or two persons from another people if you are travelling in the land and the event of death approaches you. Engage them after the prayer. If you have doubts, let them swear by God: “We will not sell our testimony for any price, even if he was a near relative, and we will not conceal God’s testimony, for then we would be sinners.”
