30:7
يَعْلَمُونَ ظَـٰهِرًا مِّنَ ٱلْحَيَوٰةِ ٱلدُّنْيَا وَهُمْ عَنِ ٱلْـَٔاخِرَةِ هُمْ غَـٰفِلُونَ
yaʿlamūna ẓāhiran mina l-ḥayati l-dun'yā wahum ʿani l-ākhirati hum ghāfilūna
they only know the outer surface of this present life and are heedless of the life to come.
They know only the outside appearance of the life of the world (i.e. the matters of their livelihood, like irrigating or sowing or reaping, etc.), and they are heedless of the Hereafter.
