30:51

وَلَئِنْ أَرْسَلْنَا رِيحًا فَرَأَوْهُ مُصْفَرًّا لَّظَلُّوا مِن بَعْدِهِ يَكْفُرُونَ

Transliteration:

Wala-in arsalna reehan faraawhu musfarran lathalloo min baAAdihi yakfuroona

Word by Word:

But if We sent a wind and they see it turn yellow, certainly they continue after it (in) disbelief.

Translations:

But thus it is: if We send a wind [that scorches their land], and they see it turn yellow, they begin, after that [erstwhile joy], to deny the truth [of Our almightiness and grace]!

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

And if We sent a wind and they beheld it yellow, they verily would still continue in their disbelief.

And if We send a wind and they see it yellow, they would after that certainly continue to disbelieve.

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