وَمَنۡ أَظۡلَمُ مِمَّنِ ٱفۡتَرَىٰ عَلَى ٱللَّهِ كَذِبًا أَوۡ كَذَّبَ بِٱلۡحَقِّ لَمَّا جَآءَهُۥٓۚ أَلَيۡسَ فِي جَهَنَّمَ مَثۡوٗى لِّلۡكَٰفِرِينَ
And who does more wrong than he who invents a lie against Allah or denies the truth (Muhammad SAW and his doctrine of Islamic Monotheism and this Quran), when it comes to him? Is there not a dwelling in Hell for disbelievers (in the Oneness of Allah and in His Messenger Muhammad SAW)?
وَٱلَّذِينَ جَٰهَدُواْ فِينَا لَنَهۡدِيَنَّهُمۡ سُبُلَنَاۚ وَإِنَّ ٱللَّهَ لَمَعَ ٱلۡمُحۡسِنِينَ
As for those who strive hard in Us (Our Cause), We will surely guide them to Our Paths (i.e. Allah's Religion - Islamic Monotheism). And verily, Allah is with the Muhsinun (good doers)."
