Say: "He hath power to send calamities on you, from above and below, or to cover you with confusion in party strife, giving you a taste of mutual vengeance - each from the other." See how We explain the signs by various (symbols); that they may understand.
When thou seest men engaged in vain discourse about Our signs, turn away from them unless they turn to a different theme. If Satan ever makes thee forget, then after recollection, sit not thou in the company of those who do wrong.
