31:6Among the people is he who trades in distracting tales; intending, without knowledge, to lead away from God’s way, and to make a mockery of it. These will have a humiliating punishment.

31:15But if they strive to have you associate with Me something of which you have no knowledge, do not obey them. But keep them company in this life, in kindness, and follow the path of him who turns to Me. Then to Me is your return; and I will inform you of what you used to do.

31:20Do you not see how God placed at your service everything in the heavens and the earth? How He showered you with His blessings, both outward and inward? Yet among the people is he who argues about God without knowledge, without guidance, and without an enlightening Scripture.

31:34With God rests the knowledge of the Hour. He sends down the rain, and He knows what the wombs contain. No soul knows what it will reap tomorrow, and no soul knows in what land it will die. God is All-Knowing, Well-Informed.
