Quran 30:51 — Surah Ar-Rum, ayah 51

وَلَئِنۡ أَرۡسَلۡنَا رِيحٗا فَرَأَوۡهُ مُصۡفَرّٗا لَّظَلُّواْ مِنۢ بَعۡدِهِۦ يَكۡفُرُونَ

But if We should send a [bad] wind and they saw [their crops] turned yellow, they would remain thereafter disbelievers

A da pošaljemo vjetar i da oni vide da je sve požutjelo, oni bi, i poslije toga, blagodati poricali.
