الإِسۡرَاءِ · 59

وَمَا مَنَعَنَآ أَن نُّرۡسِلَ بِٱلۡأٓيَٰتِ إِلَّآ أَن كَذَّبَ بِهَا ٱلۡأَوَّلُونَۚ وَءَاتَيۡنَا ثَمُودَ ٱلنَّاقَةَ مُبۡصِرَةࣰ فَظَلَمُواْ بِهَاۚ وَمَا نُرۡسِلُ بِٱلۡأٓيَٰتِ إِلَّا تَخۡوِيفࣰ ا

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)
