وَلَوْ شِئْنَا لَءَاتَيْنَا كُلَّ نَفْسٍ هُدَىٰهَا وَلَٰكِنْ حَقَّ ٱلْقَوْلُ مِنِّى لَأَمْلَأَنَّ جَهَنَّمَ مِنَ ٱلْجِنَّةِ وَٱلنَّاسِ أَجْمَعِينَ
And if We had so willed, We could have given every soul its guidance, but the word from Me concerning evildoers took effect: that I will fill hell with the jinn and mankind together.
