سَنُريهِم آياتِنا فِي الآفاقِ وَفي أَنفُسِهِم حَتّىٰ يَتَبَيَّنَ لَهُم أَنَّهُ الحَقُّ ۗ أَوَلَم يَكفِ بِرَبِّكَ أَنَّهُ عَلىٰ كُلِّ شَيءٍ شَهيدٌ

We will show them Our signs on the horizons and within themselves, until it becomes clear to them that it’s the truth. Does it not suffice that your Lord is a Witness over everything?
