(Al-Qalam) 68 : 44
فَذَرْنِي وَمَنْ يُكَذِّبُ بِهَٰذَا الْحَدِيثِ ۖ سَنَسْتَدْرِجُهُمْ مِنْ حَيْثُ لَا يَعْلَمُونَ
So you leave Me and the one who rejects this Speech, We will seize them step by step in a manner they do not know it.
The Speech mentioned in the verse is Adhikr. All deeds of those who hide and reject It are in futile. The one who gives first preference to Adhikr will only become serving Allah. It is told repeatedly for ten times in Surah 77 that the ‘Vaile’ valley is for those who reject Adhikr. See explanation 10: 60-61; 52: 46; and 64: 10.
