Surely those who have rejected the advice (the Qur’ān) when it came to them (are the ones who adopted perversity, and are not hidden from Us). And surely, it is an unassailable book
Nothing is being said to you but what has been said to the messengers before you. Your Lord is certainly the Lord of forgiveness and the Lord of painful punishment.
Had We made it a non-Arabic Qur’ān, they would have said, “Why are its verses not clearly explained? Is it a non-Arabic (book) and an Arab (messenger)?” Say, “For those who believe, it is guidance and cure. As for those who do not believe, there is deafness in their ears, and for them it is blindness. Such people are being called from a distant place.”
And We gave Mūsā the book, then it was disputed (as well). But for a word that had already come from your Lord, the matter would have been decided between them. They are in confounding doubt about it.
If someone acts righteously, he does so for the benefit of his own soul, and if someone commits evil, he does so against it. Your Lord is not unjust to His servants.
To Him alone the knowledge of the Hour (the exact time of Doomsday) is to be referred. No fruits come out of their sheaths, nor does a female conceive a baby, nor does she deliver it, but with His knowledge. And (remember) the Day when He will call them: “Where are My partners?” They will say, “We declare to you that no one of us is to testify (that you have partners).”
And if We give him a taste of some mercy from Us after some hardship that has touched him, he will surely say, “This is my right. And I do not think the Hour (the Day of Judgment) is going to occur. And even if I am brought back to my Lord, I will surely have the best (life) with Him (too).”So, We will let the disbelievers know what they did, and let them taste a stern punishment.
