﴿ وَلَقَدْ عَلِمْتُمُ ٱلنَّشْأَةَ ٱلْأُولَىٰ فَلَوْلَا تَذَكَّرُونَ ﴾

“And [since] you are indeed aware of the [miracle of your] coming into being in the first instance - why, then, do you not bethink yourselves [of Us]?”

For verily you have known the first creation al-nashā’ata a variant reading has al-nash’ata why then will you not remember? tadhakkarūna the original second tā’ of tatadhakkarūna has been assimilated with the dhāl.
