Then bring upon us the (calamity) with which thou dost threaten us, if thou art telling the truth?" 22 Said he: "Knowledge [of when it is to befall you] rests with God alone: I but convey unto you the message with which I have been entrusted; but I see that you are people ignorant [of right and wrong]!" 23 So, when they saw it in the shape of a dense cloud approaching their valleys, they exclaimed, "This is only a heavy cloud which will bring us [welcome] rain!"
