Ibn Kathir (Abridged) التفسير: هود آية 102

إِنَّ أَخْذَهُ أَلِيمٌ شَدِيدٌ

(Verily, His punishment is painful (and) severe.) In the Two Sahihs, it is recorded that Abu Musa said that the Messenger of Allah ﷺ said,

«إِنَّ اللهَ لَيُمْلِي لِلظَّالِمِ حَتَّى إِذَا أَخَذَهُ لَمْ يُفْلِتْه»

(Verily, Allah gives respite to a wrongdoer until He seizes him and he cannot escape.) Then the Messenger of Allah ﷺ recited,

وَكَذلِكَ أَخْذُ رَبِّكَ إِذَا أَخَذَ الْقُرَى وَهِىَ ظَـلِمَةٌ

(Such is the punishment of your Lord when He seizes the towns while they are doing wrong. )
