16:94And do not use your oaths to deceive one another, so that a foot may not slip after being firm, and you taste misery because you hindered from God’s path, and incur a terrible torment.

16:106Whoever renounces faith in God after having believed—except for someone who is compelled, while his heart rests securely in faith—but whoever willingly opens up his heart to disbelief—upon them falls wrath from God, and for them is a tremendous torment.
