And they say, "Why has a sign not been sent down to him from his Lord?" Say, "Indeed, Allah is Able to send down a sign, but most of them do not know."
And there is no creature on [or within] the earth or bird that flies with its wings except [that they are] communities like you. We have not neglected in the Register a thing. Then unto their Lord they will be gathered.
But those who deny Our verses are deaf and dumb within darknesses. Whomever Allah wills - He leaves astray; and whomever He wills - He puts him on a straight path.
Say, "Have you considered: if there came to you the punishment of Allah or there came to you the Hour - is it other than Allah you would invoke, if you should be truthful?"
No, it is Him [alone] you would invoke, and He would remove that for which you invoked Him if He willed, and you would forget what you associate [with Him].
And We have already sent [messengers] to nations before you, [O Muhammad]; then We seized them with poverty and hardship that perhaps they might humble themselves [to Us].
Then why, when Our punishment came to them, did they not humble themselves? But their hearts became hardened, and Satan made attractive to them that which they were doing.
So when they forgot that by which they had been reminded, We opened to them the doors of every [good] thing until, when they rejoiced in that which they were given, We seized them suddenly, and they were [then] in despair.
Say, "Have you considered: if Allah should take away your hearing and your sight and set a seal upon your hearts, which deity other than Allah could bring them [back] to you?" Look how we diversify the verses; then they [still] turn away.
And We send not the messengers except as bringers of good tidings and warners. So whoever believes and reforms - there will be no fear concerning them, nor will they grieve.
Say, [O Muhammad], "I do not tell you that I have the depositories [containing the provision] of Allah or that I know the unseen, nor do I tell you that I am an angel. I only follow what is revealed to me." Say, "Is the blind equivalent to the seeing? Then will you not give thought?"
And warn by the Qur'an those who fear that they will be gathered before their Lord - for them besides Him will be no protector and no intercessor - that they might become righteous.
And do not send away those who call upon their Lord morning and afternoon, seeking His countenance. Not upon you is anything of their account and not upon them is anything of your account. So were you to send them away, you would [then] be of the wrongdoers.
And thus We have tried some of them through others that the disbelievers might say, "Is it these whom Allah has favored among us?" Is not Allah most knowing of those who are grateful?
And when those come to you who believe in Our verses, say, "Peace be upon you. Your Lord has decreed upon Himself mercy: that any of you who does wrong out of ignorance and then repents after that and corrects himself - indeed, He is Forgiving and Merciful."
Say, "Indeed, I have been forbidden to worship those you invoke besides Allah." Say, "I will not follow your desires, for I would then have gone astray, and I would not be of the [rightly] guided."
Say, "Indeed, I am on clear evidence from my Lord, and you have denied it. I do not have that for which you are impatient. The decision is only for Allah. He relates the truth, and He is the best of deciders."
