﴿ لِّنَفْتِنَهُمْ فِيهِ ۚ وَمَن يُعْرِضْ عَن ذِكْرِ رَبِّهِۦ يَسْلُكْهُ عَذَابًۭا صَعَدًۭا ﴾

“so as to test them by this means: for he who shall turn away from the remembrance of his Sustainer, him will He cause to undergo suffering most grievous.”

so that We may try them test them therein and so know through knowledge outwardly manifested the nature of their gratitude. And whoever turns away from the remembrance of his Lord from the Qur’ān We will admit him naslukhu or read first person yaslukhu ‘He will admit him’ into a tortuous chastisement.
