﴿ أَيْنَمَا تَكُونُوا۟ يُدْرِككُّمُ ٱلْمَوْتُ وَلَوْ كُنتُمْ فِى بُرُوجٍۢ مُّشَيَّدَةٍۢ ۗ وَإِن تُصِبْهُمْ حَسَنَةٌۭ يَقُولُوا۟ هَٰذِهِۦ مِنْ عِندِ ٱللَّهِ ۖ وَإِن تُصِبْهُمْ سَيِّئَةٌۭ يَقُولُوا۟ هَٰذِهِۦ مِنْ عِندِكَ ۚ قُلْ كُلٌّۭ مِّنْ عِندِ ٱللَّهِ ۖ فَمَالِ هَٰٓؤُلَآءِ ٱلْقَوْمِ لَا يَكَادُونَ يَفْقَهُونَ حَدِيثًۭا ﴾

“Wherever you may be, death will overtake you - even though you be in towers raised high. "Yet, when a good thing happens to them, some [people] say, "This is from God," whereas when evil befalls them, they say, "This is from thee [O fellow­man]!” Say: "All is from God." What, then, is amiss with these people that they are in no wise near to grasping the truth of what they are told?”
