quran:30:7 –

They know what is apparent of the worldly life, but they, of the Hereafter, are unaware.  

They know ˹merely˺ an outward aspect of the life of this world, that is to say, its various means of ˹securing˺ livelihood, such as commerce, agriculture, construction and cultivation and so on; but they, of the Hereafter, they are oblivious (this repetition of hum, ‘they’, is for emphasis).
القرآن:٣٠:٧ –

يَعْلَمُونَ ظَاهِرًا مِنَ الْحَيَاةِ الدُّنْيَا وَهُمْ عَنِ الْآخِرَةِ هُمْ غَافِلُونَ  

{يعلمون ظاهراً من الحياة الدنيا} أي معايشها من التجارة والزراعة والبناء والغرس وغير ذلك {وهم عن الآخرة هم غافلون} إعادة هم تأكيد.
