قَالَ ٱلْمَلَأُ ٱلَّذِينَ ٱسْتَكْبَرُوا۟ مِن قَوْمِهِۦ لِلَّذِينَ ٱسْتُضْعِفُوا۟ لِمَنْ ءَامَنَ مِنْهُمْ أَتَعْلَمُونَ أَنَّ صَـٰلِحًا مُّرْسَلٌ مِّن رَّبِّهِۦ ۚ قَالُوٓا۟ إِنَّا بِمَآ أُرْسِلَ بِهِۦ مُؤْمِنُونَ

وَإِلَىٰ ثَمُودَ أَخَاهُمْ صَـٰلِحًا ۗ قَالَ يَـٰقَوْمِ ٱعْبُدُوا۟ ٱللَّهَ مَا لَكُم مِّنْ إِلَـٰهٍ غَيْرُهُۥ ۖ قَدْ جَآءَتْكُم بَيِّنَةٌ مِّن رَّبِّكُمْ ۖ هَـٰذِهِۦ نَاقَةُ ٱللَّهِ لَكُمْ ءَايَةً ۖ فَذَرُوهَا تَأْكُلْ فِىٓ أَرْضِ ٱللَّهِ ۖ وَلَا تَمَسُّوهَا بِسُوٓءٍ فَيَأْخُذَكُمْ عَذَابٌ أَلِيمٌ
And to the Thamud [We sent] their brother Salih. He said, "O my people, worship Allah; you have no deity other than Him. There has come to you clear evidence from your Lord. This is the she-camel of Allah [sent] to you as a sign. So leave her to eat within Allah 's land and do not touch her with harm, lest there seize you a painful punishment.
وَٱذْكُرُوٓا۟ إِذْ جَعَلَكُمْ خُلَفَآءَ مِنۢ بَعْدِ عَادٍ وَبَوَّأَكُمْ فِى ٱلْأَرْضِ تَتَّخِذُونَ مِن سُهُولِهَا قُصُورًا وَتَنْحِتُونَ ٱلْجِبَالَ بُيُوتًا ۖ فَٱذْكُرُوٓا۟ ءَالَآءَ ٱللَّهِ وَلَا تَعْثَوْا۟ فِى ٱلْأَرْضِ مُفْسِدِينَ
And remember when He made you successors after the 'Aad and settled you in the land, [and] you take for yourselves palaces from its plains and carve from the mountains, homes. Then remember the favors of Allah and do not commit abuse on the earth, spreading corruption."
قَالَ ٱلَّذِينَ ٱسْتَكْبَرُوٓا۟ إِنَّا بِٱلَّذِىٓ ءَامَنتُم بِهِۦ كَـٰفِرُونَ
Said those who were arrogant, "Indeed we, in that which you have believed, are disbelievers."
فَعَقَرُوا۟ ٱلنَّاقَةَ وَعَتَوْا۟ عَنْ أَمْرِ رَبِّهِمْ وَقَالُوا۟ يَـٰصَـٰلِحُ ٱئْتِنَا بِمَا تَعِدُنَآ إِن كُنتَ مِنَ ٱلْمُرْسَلِينَ
So they hamstrung the she-camel and were insolent toward the command of their Lord and said, "O Salih, bring us what you promise us, if you should be of the messengers."
