45:19
إِنَّهُمْ لَن يُغْنُوا۟ عَنكَ مِنَ ٱللَّهِ شَيْـًٔا ۚ وَإِنَّ ٱلظَّـٰلِمِينَ بَعْضُهُمْ أَوْلِيَآءُ بَعْضٍ ۖ وَٱللَّهُ وَلِىُّ ٱلْمُتَّقِينَ
Indeed, they will never avail you against Allah at all. And indeed, the wrongdoers are allies of one another; but Allah is the protector of the righteous.

وَءَاتَيْنَـٰهُم بَيِّنَـٰتٍ مِّنَ ٱلْأَمْرِ ۖ فَمَا ٱخْتَلَفُوٓا۟ إِلَّا مِنۢ بَعْدِ مَا جَآءَهُمُ ٱلْعِلْمُ بَغْيًۢا بَيْنَهُمْ ۚ إِنَّ رَبَّكَ يَقْضِى بَيْنَهُمْ يَوْمَ ٱلْقِيَـٰمَةِ فِيمَا كَانُوا۟ فِيهِ يَخْتَلِفُونَ
And We gave them clear proofs of the matter [of religion]. And they did not differ except after knowledge had come to them - out of jealous animosity between themselves. Indeed, your Lord will judge between them on the Day of Resurrection concerning that over which they used to differ.
ثُمَّ جَعَلْنَـٰكَ عَلَىٰ شَرِيعَةٍ مِّنَ ٱلْأَمْرِ فَٱتَّبِعْهَا وَلَا تَتَّبِعْ أَهْوَآءَ ٱلَّذِينَ لَا يَعْلَمُونَ
Then We put you, [O Muhammad], on an ordained way concerning the matter [of religion]; so follow it and do not follow the inclinations of those who do not know.
هَـٰذَا بَصَـٰٓئِرُ لِلنَّاسِ وَهُدًى وَرَحْمَةٌ لِّقَوْمٍ يُوقِنُونَ
This [Qur'an] is enlightenment for mankind and guidance and mercy for a people who are certain [in faith].
أَمْ حَسِبَ ٱلَّذِينَ ٱجْتَرَحُوا۟ ٱلسَّيِّـَٔاتِ أَن نَّجْعَلَهُمْ كَٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّـٰلِحَـٰتِ سَوَآءً مَّحْيَاهُمْ وَمَمَاتُهُمْ ۚ سَآءَ مَا يَحْكُمُونَ
Or do those who commit evils think We will make them like those who have believed and done righteous deeds - [make them] equal in their life and their death? Evil is that which they judge.
