Read Ruku 252 of the Quran

ٱلْحَمْدُ لِلَّهِ ٱلَّذِىٓ أَنزَلَ عَلَىٰ عَبْدِهِ ٱلْكِتَـٰبَ وَلَمْ يَجْعَل لَّهُۥ عِوَجَا ۜ ﴿١﴾

[All] praise is [due] to Allah, who has sent down upon His Servant the Book and has not made therein any deviance.

قَيِّمًۭا لِّيُنذِرَ بَأْسًۭا شَدِيدًۭا مِّن لَّدُنْهُ وَيُبَشِّرَ ٱلْمُؤْمِنِينَ ٱلَّذِينَ يَعْمَلُونَ ٱلصَّـٰلِحَـٰتِ أَنَّ لَهُمْ أَجْرًا حَسَنًۭا ﴿٢﴾

[He has made it] straight, to warn of severe punishment from Him and to give good tidings to the believers who do righteous deeds that they will have a good reward

مَّـٰكِثِينَ فِيهِ أَبَدًۭا ﴿٣﴾

In which they will remain forever

وَيُنذِرَ ٱلَّذِينَ قَالُوا۟ ٱتَّخَذَ ٱللَّهُ وَلَدًۭا ﴿٤﴾

And to warn those who say, "Allah has taken a son."

مَّا لَهُم بِهِۦ مِنْ عِلْمٍۢ وَلَا لِـَٔابَآئِهِمْ ۚ كَبُرَتْ كَلِمَةًۭ تَخْرُجُ مِنْ أَفْوَٰهِهِمْ ۚ إِن يَقُولُونَ إِلَّا كَذِبًۭا ﴿٥﴾

They have no knowledge of it, nor had their fathers. Grave is the word that comes out of their mouths; they speak not except a lie.

فَلَعَلَّكَ بَـٰخِعٌۭ نَّفْسَكَ عَلَىٰٓ ءَاثَـٰرِهِمْ إِن لَّمْ يُؤْمِنُوا۟ بِهَـٰذَا ٱلْحَدِيثِ أَسَفًا ﴿٦﴾

Then perhaps you would kill yourself through grief over them, [O Muhammad], if they do not believe in this message, [and] out of sorrow.

إِنَّا جَعَلْنَا مَا عَلَى ٱلْأَرْضِ زِينَةًۭ لَّهَا لِنَبْلُوَهُمْ أَيُّهُمْ أَحْسَنُ عَمَلًۭا ﴿٧﴾

Indeed, We have made that which is on the earth adornment for it that We may test them [as to] which of them is best in deed.

وَإِنَّا لَجَـٰعِلُونَ مَا عَلَيْهَا صَعِيدًۭا جُرُزًا ﴿٨﴾

And indeed, We will make that which is upon it [into] a barren ground.

أَمْ حَسِبْتَ أَنَّ أَصْحَـٰبَ ٱلْكَهْفِ وَٱلرَّقِيمِ كَانُوا۟ مِنْ ءَايَـٰتِنَا عَجَبًا ﴿٩﴾

Or have you thought that the companions of the cave and the inscription were, among Our signs, a wonder?

إِذْ أَوَى ٱلْفِتْيَةُ إِلَى ٱلْكَهْفِ فَقَالُوا۟ رَبَّنَآ ءَاتِنَا مِن لَّدُنكَ رَحْمَةًۭ وَهَيِّئْ لَنَا مِنْ أَمْرِنَا رَشَدًۭا ﴿١٠﴾

[Mention] when the youths retreated to the cave and said, "Our Lord, grant us from Yourself mercy and prepare for us from our affair right guidance."

فَضَرَبْنَا عَلَىٰٓ ءَاذَانِهِمْ فِى ٱلْكَهْفِ سِنِينَ عَدَدًۭا ﴿١١﴾

So We cast [a cover of sleep] over their ears within the cave for a number of years.

ثُمَّ بَعَثْنَـٰهُمْ لِنَعْلَمَ أَىُّ ٱلْحِزْبَيْنِ أَحْصَىٰ لِمَا لَبِثُوٓا۟ أَمَدًۭا ﴿١٢﴾

Then We awakened them that We might show which of the two factions was most precise in calculating what [extent] they had remained in time.
