O children of Adam! if there come to you messengers from among you relating to you My communications, then whoever shall guard (against evil) and act aright-- they shall have no fear nor shall they grieve.

And when Our clear communications are recited to them, those who hope not for Our meeting say: Bring a Quran other than this or change it. Say: It does not beseem me that I should change it of myself; I follow naught but what is revealed to me; surely I fear, if I disobey my Lord, the punishment of a mighty day.

Most surely there is a sign in this for him who fears the chastisement of the hereafter; this is a day on which the people shall be gathered together and this is a day that shall be witnessed.

And nothing could have hindered Us that We should send signs except that the ancients rejected them; and We gave to Samood the she-camel-- a manifest sign-- but on her account they did injustice, and We do not send signs but to make (men) fear.

And one of His signs is that He shows you the lightning for fear and for hope, and sends down water from the clouds then gives life therewith to the earth after its death; most surely there are signs in this for a people who understand

He sets forth to you a parable relating to yourselves: Have you among those whom your right hands possess partners in what We have given you for sustenance, so that with respect to it you are alike; you fear them as you fear each other? Thus do We make the communications distinct for a people who understand.

And We left therein a sign for those who fear the painful punishment.
