Their likeness is as the likeness of the one who kindled a fire, and when it illuminated what was around him, Allah took away their light.

And sometimes they bring the singular in place of the dual,

and among its examples is His statement - the Exalted -:

Except that Allah and His Messenger enriched them out of His bounty.

If I am upon a clear proof from my Lord and He has given me mercy from Himself, but it has been obscured from you

And the original was fa-umiyata, so He made it singular because they two are like a single thing, and similar to it is "Allah and His Messenger know best."

Replacing the condition, the consequence, and the answer of the oath with other than that:

- And sometimes the nature of speech requires that the consequence be mentioned in the form of a consequence and the condition in the form of a condition,

and the answer of the oath in the form of the answer of the oath, but the speech is altered so this part - whether it is a consequence, a condition, or an answer to the oath - is mentioned in the form of an independent, resumed sentence,

and at that point the inclination is towards the meaning, and an indication stands there pointing to that in one way or another.

From examples of that is His statement - the Exalted -: {By those who extract with violence} {And those who arrange the matter (5) The Day the quaking one will quake}.

So the meaning is: that the resurrection and gathering are true, indicated by His statement - the Exalted -: {The Day the quaking one will quake}.
