فَإِنَّمَا هِيَ زَجْرَةٌ وَاحِدَةٌ فَإِذَا هُمْ يَنظُرُونَ

Transliteration:

Fa-innama hiya zajratun wahidatun fa-itha hum yanthuroona

Word by Word:

Then only it (will be) a cry single, then, behold! They will see.

Translations:

for that [resurrection which they deride] will be [upon them of a sudden, as if it were] but a single accusing cry - and then, lo! they will begin to see [the truth]

Then it will be a single (compelling) cry; and behold, they will begin to see!

There is but one Shout, and lo! they behold,

So it will be but one cry, when lo! they will see.

It will be only one shout, and at once they will be observing.
