﴿ إِن تُصِبْكَ حَسَنَةٌۭ تَسُؤْهُمْ ۖ وَإِن تُصِبْكَ مُصِيبَةٌۭ يَقُولُوا۟ قَدْ أَخَذْنَآ أَمْرَنَا مِن قَبْلُ وَيَتَوَلَّوا۟ وَّهُمْ فَرِحُونَ ﴾
“Should good fortune alight on thee, [O Prophet,] it will grieve them; and should misfortune befall thee, they will say [to themselves], "We have already taken our precautions beforehand!" - and will turn away, and will rejoice.”
