Stylistic Echo and Comparison to Quraysh
The phrase pattern وَلَقَدْ جَاءَ (“And certainly there came …”) appears earlier in the Surah regarding Quraysh, and here it is used to state that the warnings came to Aal Fir’awn. This sets up a comparison between the case of Quraysh and the people of Fir’awn, subtly tying the historical accounts to Quraysh who are being addressed.
وَلَقَدْ جَاءَهُم مِّنَ الْأَنبَاءِ مَا فِيهِ مُزْدَجَرٌ
“And there has certainly come from them from the news of events (i.e., of previous nations) that which contains a deterrent”.
فَمَا تُغْنِ النُّذُرُ
“But the warnings did not benefit (them)”.
In contrast, our ayah states that the warnings came to Aal Fir’awn, aligning the narrative thread while sharpening the focus of admonition.
