Read Ruku 10 of the Quran

أَوَلَا يَعْلَمُونَ أَنَّ ٱللَّهَ يَعْلَمُ مَا يُسِرُّونَ وَمَا يُعْلِنُونَ ﴿٧٧﴾

But do they not know that Allah knows what they conceal and what they declare?

وَمِنْهُمْ أُمِّيُّونَ لَا يَعْلَمُونَ ٱلْكِتَـٰبَ إِلَّآ أَمَانِىَّ وَإِنْ هُمْ إِلَّا يَظُنُّونَ ﴿٧٨﴾

And among them are unlettered ones who do not know the Scripture except in wishful thinking, but they are only assuming.

فَوَيْلٌۭ لِّلَّذِينَ يَكْتُبُونَ ٱلْكِتَـٰبَ بِأَيْدِيهِمْ ثُمَّ يَقُولُونَ هَـٰذَا مِنْ عِندِ ٱللَّهِ لِيَشْتَرُوا۟ بِهِۦ ثَمَنًۭا قَلِيلًۭا ۖ فَوَيْلٌۭ لَّهُم مِّمَّا كَتَبَتْ أَيْدِيهِمْ وَوَيْلٌۭ لَّهُم مِّمَّا يَكْسِبُونَ ﴿٧٩﴾

So woe to those who write the "scripture" with their own hands, then say, "This is from Allah," in order to exchange it for a small price. Woe to them for what their hands have written and woe to them for what they earn.

وَقَالُوا۟ لَن تَمَسَّنَا ٱلنَّارُ إِلَّآ أَيَّامًۭا مَّعْدُودَةًۭ ۚ قُلْ أَتَّخَذْتُمْ عِندَ ٱللَّهِ عَهْدًۭا فَلَن يُخْلِفَ ٱللَّهُ عَهْدَهُۥٓ ۖ أَمْ تَقُولُونَ عَلَى ٱللَّهِ مَا لَا تَعْلَمُونَ ﴿٨٠﴾

And they say, "Never will the Fire touch us, except for a few days." Say, "Have you taken a covenant with Allah? For Allah will never break His covenant. Or do you say about Allah that which you do not know?"

بَلَىٰ مَن كَسَبَ سَيِّئَةًۭ وَأَحَـٰطَتْ بِهِۦ خَطِيٓـَٔتُهُۥ فَأُو۟لَـٰٓئِكَ أَصْحَـٰبُ ٱلنَّارِ ۖ هُمْ فِيهَا خَـٰلِدُونَ ﴿٨١﴾

Yes, whoever earns evil and his sin has encompassed him - those are the companions of the Fire; they will abide therein eternally.

وَٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّـٰلِحَـٰتِ أُو۟لَـٰٓئِكَ أَصْحَـٰبُ ٱلْجَنَّةِ ۖ هُمْ فِيهَا خَـٰلِدُونَ ﴿٨٢﴾

But they who believe and do righteous deeds - those are the companions of Paradise; they will abide therein eternally.
