وَمَا مَنَعَنَآ أَن نُّرْسِلَ بِٱلْءَايَٰتِ إِلَّآ أَن كَذَّبَ بِهَا ٱلْأَوَّلُونَ ۚ وَءَاتَيْنَا ثَمُودَ ٱلنَّاقَةَ مُبْصِرَةًۭ فَظَلَمُوا۟ بِهَا ۚ وَمَا نُرْسِلُ بِٱلْءَايَٰتِ إِلَّا تَخْوِيفًۭا
Naught hindereth Us from sending portents save that the folk of old denied them. And We gave Thamud the she-camel - a clear portent save to warn.
Surah Al-Israa(17:59)
