Surah Al-A'raaf, Verse 75
قَالَ ٱلْمَلَأُ ٱلَّذِينَ ٱسْتَكْبَرُوا۟ مِن قَوْمِهِۦ لِلَّذِينَ ٱسْتُضْعِفُوا۟ لِمَنْ ءَامَنَ مِنْهُمْ أَتَعْلَمُونَ أَنَّ صَٰلِحًۭا مُّرْسَلٌۭ مِّن رَّبِّهِۦ ۚ قَالُوٓا۟ إِنَّا بِمَآ أُرْسِلَ بِهِۦ مُؤْمِنُونَ
Translation — Sahih International
Said the eminent ones who were arrogant among his people to those who were oppressed - to those who believed among them, "Do you [actually] know that Salih is sent from his Lord?" They said, "Indeed we, in that with which he was sent, are believers."
