Luqman
وَمَن كَفَرَ فَلَا يَحْزُنكَ كُفْرُهُۥٓ ۚ إِلَيْنَا مَرْجِعُهُمْ فَنُنَبِّئُهُم بِمَا عَمِلُوٓا۟ ۚ إِنَّ ٱللَّهَ عَلِيمٌۢ بِذَاتِ ٱلصُّدُورِ
And whoever has disbelieved - let not his disbelief grieve you. To Us is their return, and We will inform them of what they did. Indeed, Allah is Knowing of that within the breasts.

وَإِذَا قِيلَ لَهُمُ ٱتَّبِعُوا۟ مَآ أَنزَلَ ٱللَّهُ قَالُوا۟ بَلْ نَتَّبِعُ مَا وَجَدْنَا عَلَيْهِ ءَابَآءَنَآ ۚ أَوَلَوْ كَانَ ٱلشَّيْطَـٰنُ يَدْعُوهُمْ إِلَىٰ عَذَابِ ٱلسَّعِيرِ
And when it is said to them, "Follow what Allah has revealed," they say, "Rather, we will follow that upon which we found our fathers." Even if Satan was inviting them to the punishment of the Blaze?
۞ وَمَن يُسْلِمْ وَجْهَهُۥٓ إِلَى ٱللَّهِ وَهُوَ مُحْسِنٌ فَقَدِ ٱسْتَمْسَكَ بِٱلْعُرْوَةِ ٱلْوُثْقَىٰ ۗ وَإِلَى ٱللَّهِ عَـٰقِبَةُ ٱلْأُمُورِ
And whoever submits his face to Allah while he is a doer of good - then he has grasped the most trustworthy handhold. And to Allah will be the outcome of [all] matters.
نُمَتِّعُهُمْ قَلِيلًا ثُمَّ نَضْطَرُّهُمْ إِلَىٰ عَذَابٍ غَلِيظٍ
We grant them enjoyment for a little; then We will force them to a massive punishment.
وَلَئِن سَأَلْتَهُم مَّنْ خَلَقَ ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضَ لَيَقُولُنَّ ٱللَّهُ ۚ قُلِ ٱلْحَمْدُ لِلَّهِ ۚ بَلْ أَكْثَرُهُمْ لَا يَعْلَمُونَ
And if you asked them, "Who created the heavens and earth?" they would surely say, "Allah." Say, "[All] praise is [due] to Allah "; but most of them do not know.
