Surah Al-A'raf, ayah 90

وَقَالَ ٱلۡمَلَأُ ٱلَّذِينَ كَفَرُواْ مِن قَوۡمِهِۦ لَئِنِ ٱتَّبَعۡتُمۡ شُعَيۡبًا إِنَّكُمۡ إِذٗا لَّخَٰسِرُونَ ٩٠

Waqālal-mala'ul-ladhīna kafarū min qawmihī la init-taba'tum shu'ayban innakum idhal lakhāsirūn

Said the eminent ones who disbelieved among his people, "If you should follow Shuʿayb, indeed, you would then be losers."
