17.59. Nothing stops Us from sending the miracles (they demand as evidence in support of the Messenger's claim to be appointed by God) except that (many among the) former generations rejected them as false (and were destroyed). We had given the Thamūd the she-camel as a visible sign (miracle), but they did wrong in respect of her. We do not send such signs except to warn (and to make them aware of a possible destruction, and eternal punishment).

وَمَا مَنَعَنَا أَن نُّرْسِلَ بِالآيَاتِ إِلاَّ أَن كَذَّبَ بِهَا الأَوَّلُونَ وَآتَيْنَا ثَمُودَ النَّاقَةَ مُبْصِرَةً فَظَلَمُواْ بِهَا وَمَا نُرْسِلُ بِالآيَاتِ إِلاَّ تَخْوِيفاً
