Surah Al-A'raf — Ayah 77 (7:77)
فَعَقَرُواْ ٱلنَّاقَةَ وَعَتَوۡاْ عَنۡ أَمۡرِ رَبِّهِمۡ وَقَالُواْ يَٰصَٰلِحُ ٱئۡتِنَا بِمَا تَعِدُنَآ إِن كُنتَ مِنَ ٱلۡمُرۡسَلِينَ ٧٧
English translation (Saheeh International)
So they hamstrung the she-camel and were insolent toward the command of their Lord and said, "O Ṣāliḥ, bring us what you promise us, if you should be of the messengers."
Brief commentary
So they killed the camel which they had been forbidden to harmfully touch, too proud to follow Allah’s command. Doubting what Ṣāliḥ had promised would happen, they mocked him saying: 'O Salih! Bring the painful punishment you have told us would afflict us, If you really are a messenger from Allah!'
