The Forgiver
لَا جَرَمَ أَنَّمَا تَدْعُونَنِىٓ إِلَيْهِ لَيْسَ لَهُۥ دَعْوَةٌ فِى ٱلدُّنْيَا وَلَا فِى ٱلْـَٔاخِرَةِ وَأَنَّ مَرَدَّنَآ إِلَى ٱللَّهِ وَأَنَّ ٱلْمُسْرِفِينَ هُمْ أَصْحَـٰبُ ٱلنَّارِ
Assuredly, that to which you invite me has no [response to a] supplication in this world or in the Hereafter; and indeed, our return is to Allah, and indeed, the transgressors will be companions of the Fire.

فَسَتَذْكُرُونَ مَآ أَقُولُ لَكُمْ ۚ وَأُفَوِّضُ أَمْرِىٓ إِلَى ٱللَّهِ ۚ إِنَّ ٱللَّهَ بَصِيرٌۢ بِٱلْعِبَادِ
