﴿ وَمَا مَنَعَنَآ أَن نُّرْسِلَ بِٱلْءَايَٰتِ إِلَّآ أَن كَذَّبَ بِهَا ٱلْأَوَّلُونَ ۚ وَءَاتَيْنَا ثَمُودَ ٱلنَّاقَةَ مُبْصِرَةًۭ فَظَلَمُوا۟ بِهَا ۚ وَمَا نُرْسِلُ بِٱلْءَايَٰتِ إِلَّا تَخْوِيفًۭا ﴾

“And nothing has prevented Us from sending [this message, like the earlier ones,] with miraculous signs [in its wake], save [Our knowledge] that the people of olden times [only too often] gave the lie to them: thus, We provided for [the tribe of] Thamud the she-camel as a light-giving portent, and they sinned against it. And never did We send those signs for any other purpose than to convey a warning.”

Nothing prevented Us from sending the signs requested by the people of Mecca except that the ancients denied them when We sent such signs and so We destroyed them if We were to send them to these people of Mecca they would deny them and would thus deserve destruction. However We have judged that they be given respite so that the mission of Muhammad (s) be completed. And We gave Thamūd the she-camel as a sign that was apparent one that was clear and evident but they wronged they disbelieved it and were therefore destroyed. And We do not send signs miracles except for deterrence to servants so that they might believe.
