"Whoever does evil will be requited for it", and when this was conveyed to the Muslims they were greatly perturbed. Thereupon Messenger of Allah ﷺ said: Be moderate and stand firm in trouble that falls to the lot of a Muslim (as that) is an expiation for him; even stumbling on the path or the pricking of a thorn (are an expiation for him). Muslim said that 'Umar b. Abd al-Rahman Muhaisin was from amongst the people of Mecca.
لَمَّا نَزَلَتْ { مَنْ يَعْمَلْ سُوءًا يُجْزَ بِهِ} بَلَغَتْ مِنَ الْمُسْلِمِينَ مَبْلَغًا شَدِيدًا فَقَالَ رَسُولُ اللَّهِ ﷺ قَارِبُوا وَسَدِّدُوا فَفِي كُلِّ مَا يُصَابُ بِهِ الْمُسْلِمُ كَفَّارَةٌ حَتَّى النَّكْبَةِ يُنْكَبُهَا أَوِ الشَّوْكَةِ يُشَاكُهَا قَالَ مُسْلِمٌ هُوَ عُمَرُ بْنُ عَبْدِ الرَّحْمَنِ بْنِ مُحَيْصِنٍ مِنْ أَهْلِ مَكَّةَ
