4:72
وَإِنَّ مِنكُمْ لَمَن لَّيُبَطِّئَنَّ فَإِنْ أَصَـٰبَتْكُم مُّصِيبَةٌ قَالَ قَدْ أَنْعَمَ ٱللَّهُ عَلَىَّ إِذْ لَمْ أَكُن مَّعَهُمْ شَهِيدًا
wa-inna minkum laman layubaṭṭi-anna fa-in aṣābatkum muṣībatun qāla qad anʿama l-lahu ʿalayya idh lam akun maʿahum shahīdan
Among you there is the sort of person who is sure to lag behind: if a calamity befalls you, he says, ‘God has been gracious to me that I was not there with them,’
There is certainly among you he who would linger behind (from fighting in Allâh’s Cause). If a misfortune befalls you, he says, "Indeed Allâh has favoured me in that I was not present among them."
