Al-A'raf 7:90

وَقَالَ ٱلْمَلَأُ ٱلَّذِينَ كَفَرُوا۟ مِن قَوْمِهِۦ لَئِنِ ٱتَّبَعْتُمْ شُعَيْبًا إِنَّكُمْ إِذًا لَّخَـٰسِرُونَ

Waqāla l-mala-u alladhīna kafarū min qawmihi la-ini ittabaʿtum shuʿayban innakum idhan lakhāsirūna

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