quran:20:126 –

˹Allah˺ will say, "Thus did Our signs come to you, and you forgot them; and thus will you this Day be forgotten."  

He will say, ‘So it, the affair, is. Our signs came to you, but you forgot them, you neglected them and did not believe in them; and so, just as you forgot Our signs, today you will be forgotten’, abandoned in the Fire.
القرآن:٢٠:١٢٦ –

قَالَ كَذَٰلِكَ أَتَتْكَ آيَاتُنَا فَنَسِيتَهَا ۖ وَكَذَٰلِكَ الْيَوْمَ تُنْسَىٰ  

{قال} الأمر {كذلك أتتك آياتنا فنسيتها} تركتها ولم تؤمن بها {وكذلك} مثل نسيانك آياتنا {اليوم تنسى} تترك في النار.
