Surah Ar-Rum (The Romans), Verse 51

وَلَىِٕنْ اَرْسَلْنَا رِیْحًا فَرَاَوْهُ مُصْفَرًّا لَّظَلُّوْا مِنْ بَعْدِهٖ یَكْفُرُوْنَ ۟

Wa la'in arsalnaa reehan fara awhu musfarral lazalloo mim ba'dihee yakfuroon

“And if We (but) send a Wind from which they see (their tilth) turn yellow,- behold, they become, thereafter, Ungrateful (Unbelievers)!”
