فَإِن كَذَّبُوكَ فَقُل رَّبُّكُمْ ذُو رَحْمَةٍ وَاسِعَةٍ وَلَا يُرَدُّ بَأْسُهُ عَنِ الْقَوْمِ الْمُجْرِمِينَ
But if they deny you, say, ‘Your Lord is dispenser of an all-embracing mercy, but His punishment will not be averted from the guilty lot.’
Agha Ali Puya Commentary
Commentary on Quran 6:147
[Pooya/Ali Commentary 6:147] The Lord of the worlds is full of all-embracing mercy, so He is not hasty in His judgement, but His wrath will not be turned back from the guilty beliers and slayers of the prophets.
