وَمَا مَنَعَنَآ أَن نُّرْسِلَ بِٱلْءَايَٰتِ إِلَّآ أَن كَذَّبَ بِهَا ٱلْأَوَّلُونَ ۚ وَءَاتَيْنَا ثَمُودَ ٱلنَّاقَةَ مُبْصِرَةًۭ فَظَلَمُوا۟ بِهَا ۚ وَمَا نُرْسِلُ بِٱلْءَايَٰتِ إِلَّا تَخْوِيفًۭا
And We refrain from sending the signs, only because the men of former generations treated them as false: We sent the she-camel to the Thamud to open their eyes, but they treated her wrongfully: We only send the Signs by way of terror (and warning from evil).
