42:21
أَمْ لَهُمْ شُرَكَـٰٓؤُا۟ شَرَعُوا۟ لَهُم مِّنَ ٱلدِّينِ مَا لَمْ يَأْذَنۢ بِهِ ٱللَّهُ ۚ وَلَوْلَا كَلِمَةُ ٱلْفَصْلِ لَقُضِىَ بَيْنَهُمْ ۗ وَإِنَّ ٱلظَّـٰلِمِينَ لَهُمْ عَذَابٌ أَلِيمٌ
Or have they other deities who have ordained for them a religion to which Allah has not consented? But if not for the decisive word, it would have been concluded between them. And indeed, the wrongdoers will have a painful punishment.

ٱللَّهُ لَطِيفٌۢ بِعِبَادِهِۦ يَرْزُقُ مَن يَشَآءُ ۖ وَهُوَ ٱلْقَوِىُّ ٱلْعَزِيزُ
Allah is Subtle with His servants; He gives provisions to whom He wills. And He is the Powerful, the Exalted in Might.
مَن كَانَ يُرِيدُ حَرْثَ ٱلْـَٔاخِرَةِ نَزِدْ لَهُۥ فِى حَرْثِهِۦ ۖ وَمَن كَانَ يُرِيدُ حَرْثَ ٱلدُّنْيَا نُؤْتِهِۦ مِنْهَا وَمَا لَهُۥ فِى ٱلْـَٔاخِرَةِ مِن نَّصِيبٍ
Whoever desires the harvest of the Hereafter - We increase for him in his harvest. And whoever desires the harvest of this world - We give him thereof, but there is not for him in the Hereafter any share.
تَرَى ٱلظَّـٰلِمِينَ مُشْفِقِينَ مِمَّا كَسَبُوا۟ وَهُوَ وَاقِعٌۢ بِهِمْ ۗ وَٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّـٰلِحَـٰتِ فِى رَوْضَاتِ ٱلْجَنَّاتِ ۖ لَهُم مَّا يَشَآءُونَ عِندَ رَبِّهِمْ ۚ ذَٰلِكَ هُوَ ٱلْفَضْلُ ٱلْكَبِيرُ
You will see the wrongdoers fearful of what they have earned, and it will [certainly] befall them. And those who have believed and done righteous deeds will be in lush regions of the gardens [in Paradise] having whatever they will in the presence of their Lord. That is what is the great bounty.
ذَٰلِكَ ٱلَّذِى يُبَشِّرُ ٱللَّهُ عِبَادَهُ ٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّـٰلِحَـٰتِ ۗ قُل لَّآ أَسْـَٔلُكُمْ عَلَيْهِ أَجْرًا إِلَّا ٱلْمَوَدَّةَ فِى ٱلْقُرْبَىٰ ۗ وَمَن يَقْتَرِفْ حَسَنَةً نَّزِدْ لَهُۥ فِيهَا حُسْنًا ۚ إِنَّ ٱللَّهَ غَفُورٌ شَكُورٌ
It is that of which Allah gives good tidings to His servants who believe and do righteous deeds. Say, [O Muhammad], "I do not ask you for this message any payment [but] only good will through kinship." And whoever commits a good deed - We will increase for him good therein. Indeed, Allah is Forgiving and Appreciative.
