Defense of honor and reputation

إِنَّ ٱلَّذِينَ جَآءُو بِٱلْإِفْكِ عُصْبَةٌ مِّنكُمْ ۚ لَا تَحْسَبُوهُ شَرًّا لَّكُم ۖ بَلْ هُوَ خَيْرٌ لَّكُمْ ۚ لِكُلِّ ٱمْرِئٍ مِّنْهُم مَّا ٱكْتَسَبَ مِنَ ٱلْإِثْمِ ۚ وَٱلَّذِى تَوَلَّىٰ كِبْرَهُۥ مِنْهُمْ لَهُۥ عَذَابٌ عَظِيمٌ

Indeed, those who came with falsehood are a group among you. Do not think it bad for you; rather, it is good for you. For every person among them is what [punishment] he has earned from the sin, and he who took upon himself the greater portion thereof - for him is a great punishment [i.e., Hellfire].

وَلَوْلَآ إِذْ سَمِعْتُمُوهُ قُلْتُم مَّا يَكُونُ لَنَآ أَن نَّتَكَلَّمَ بِهَـٰذَا سُبْحَـٰنَكَ هَـٰذَا بُهْتَـٰنٌ عَظِيمٌ

And why, when you heard it, did you not say, "It is not for us to speak of this. Exalted are You, [O Allāh]; this is a great slander"?
