وَمَا مَنَعَنَآ أَن نُّرْسِلَ بِٱلْـَٔايَـٰتِ إِلَّآ أَن كَذَّبَ بِهَا ٱلْأَوَّلُونَ ۚ وَءَاتَيْنَا ثَمُودَ ٱلنَّاقَةَ مُبْصِرَةً فَظَلَمُوا۟ بِهَا ۚ وَمَا نُرْسِلُ بِٱلْـَٔايَـٰتِ إِلَّا تَخْوِيفًا
Nothing keeps Us from sending signs except that the former peoples denied them. We gave Thamud the she-camel as an eye-opener, but they wronged her. We do not send the signs except as warning.
