3:162
أَفَمَنِ ٱتَّبَعَ رِضْوَٰنَ ٱللَّهِ كَمَنۢ بَآءَ بِسَخَطٍۢ مِّنَ ٱللَّهِ وَمَأْوَىٰهُ جَهَنَّمُ ۚ وَبِئْسَ ٱلْمَصِيرُ
So is one who pursues the pleasure of Allah like one who brings upon himself the anger of Allah and whose refuge is Hell? And wretched is the destination.

فَبِمَا رَحْمَةٍ مِّنَ اللَّهِ لِنتَ لَهُمْ
(And by the mercy of Allah, you dealt with them gently) 3:159. meaning, who would have made you this kind, if it was not Allah's mercy for you and them. Qatadah said that,
