Surah Saba, Verse 31
وَقَالَ ٱلَّذِينَ كَفَرُوا۟ لَن نُّؤْمِنَ بِهَٰذَا ٱلْقُرْءَانِ وَلَا بِٱلَّذِى بَيْنَ يَدَيْهِ ۗ وَلَوْ تَرَىٰٓ إِذِ ٱلظَّٰلِمُونَ مَوْقُوفُونَ عِندَ رَبِّهِمْ يَرْجِعُ بَعْضُهُمْ إِلَىٰ بَعْضٍ ٱلْقَوْلَ يَقُولُ ٱلَّذِينَ ٱسْتُضْعِفُوا۟ لِلَّذِينَ ٱسْتَكْبَرُوا۟ لَوْلَآ أَنتُمْ لَكُنَّا مُؤْمِنِينَ
Translation — Sahih International
And those who disbelieve say, "We will never believe in this Qur'an nor in that before it." But if you could see when the wrongdoers are made to stand before their Lord, refuting each other's words... Those who were oppressed will say to those who were arrogant, "If not for you, we would have been believers."
