The Quran root خ ط أ kh-ṭ-’

وَإِذْ قُلْنَا ادْخُلُوا هَٰذِهِ الْقَرْيَةَ فَكُلُوا مِنْهَا حَيْثُ شِئْتُمْ رَغَدًا وَادْخُلُوا الْبَابَ سُجَّدًا وَقُولُوا حِطَّةٌ نَّغْفِرْ لَكُمْ خَطَايَاكُمْ وَسَنَزِيدُ الْمُحْسِنِينَ ٥٨

خَطَايَاكُمْ khaṭāyākum · your sins

And [recall] when We said, "Enter this city [i.e., Jerusalem] and eat from it wherever you will in [ease and] abundance, and enter the gate bowing humbly and say, 'Relieve us of our burdens [i.e., sins].' We will [then] forgive your sins for you, and We will increase the doers of good [in goodness and reward]." (Surah Al-Baqarah, 2:58)

بَلَىٰ مَن كَسَبَ سَيِّئَةً وَأَحَاطَتْ بِهِ خَطِيئَتُهُ فَأُولَٰئِكَ أَصْحَابُ النَّارِ هُمْ فِيهَا خَالِدُونَ ٨١

خَطِيئَتُهُ khaṭīatuhu · his sins

Yes, [on the contrary], whoever earns evil and his sin has encompassed him - those are the companions of the Fire; they will abide therein eternally. (Surah Al-Baqarah, 2:81)

يُوسُفُ أَعْرِضْ عَنْ هَٰذَا وَاسْتَغْفِرِي لِذَنبِكِ إِنَّكِ كُنتِ مِنَ الْخَاطِئِينَ ٢٩

الْخَاطِئِينَ l-khāṭiīna · the sinful

Joseph, ignore this. And, [my wife], ask forgiveness for your sin. Indeed, you were of the sinful." (Surah Yusuf, 12:29)

لَا يُكَلِّفُ اللَّهُ نَفْسًا إِلَّا وُسْعَهَا لَهَا مَا كَسَبَتْ وَعَلَيْهَا مَا اكْتَسَبَتْ رَبَّنَا لَا تُؤَاخِذْنَا إِن نَّسِينَا أَوْ أَخْطَأْنَا رَبَّنَا وَلَا تَحْمِلْ عَلَيْنَا إِصْرًا كَمَا حَمَلْتَهُ عَلَى الَّذِينَ مِن قَبْلِنَا رَبَّنَا وَلَا تُحَمِّلْنَا مَا لَا طَاقَةَ لَنَا بِهِ وَاعْفُ عَنَّا وَاغْفِرْ لَنَا وَارْحَمْنَا أَنتَ مَوْلَانَا فَانصُرْنَا عَلَى الْقَوْمِ الْكَافِرِينَ ٢٨٦

أَخْطَأْنَا akhṭanā · we err

Allāh does not charge a soul except [with that within] its capacity. It will have [the consequence of] what [good] it has gained, and it will bear [the consequence of] what [evil] it has earned. "Our Lord, do not impose blame upon us if we have forgotten or erred. Our Lord, and lay not upon us a burden like that which You laid upon those before us. Our Lord, and burden us not with that which we have no ability to bear. And pardon us; and forgive us; and have mercy upon us. You are our protector, so give us victory over the disbelieving people." (Surah Al-Baqarah, 2:286)

وَمَا كَانَ لِمُؤْمِنٍ أَن يَقْتُلَ مُؤْمِنًا إِلَّا خَطَأً وَمَن قَتَلَ مُؤْمِنًا خَطَأً فَتَحْرِيرُ رَقَبَةٍ مُّؤْمِنَةٍ وَدِيَةٌ مُّسَلَّمَةٌ إِلَىٰ أَهْلِهِ إِلَّا أَن يَصَّدَّقُوا فَإِن كَانَ مِن قَوْمٍ عَدُوٍّ لَّكُمْ وَهُوَ مُؤْمِنٌ فَتَحْرِيرُ رَقَبَةٍ مُّؤْمِنَةٍ وَإِن كَانَ مِن قَوْمٍ بَيْنَكُمْ وَبَيْنَهُم مِّيثَاقٌ فَدِيَةٌ مُّسَلَّمَةٌ إِلَىٰ أَهْلِهِ وَتَحْرِيرُ رَقَبَةٍ مُّؤْمِنَةٍ فَمَن لَّمْ يَجِدْ فَصِيَامُ شَهْرَيْنِ مُتَتَابِعَيْنِ تَوْبَةً مِّنَ اللَّهِ وَكَانَ اللَّهُ عَلِيمًا حَكِيمًا ٩٢

خَطَأً khaṭa-an · (by) mistake

And never is it for a believer to kill a believer except by mistake. And whoever kills a believer by mistake - then the freeing of a believing slave and a compensation payment [diyah] presented to his [i.e., the deceased's] family [is required], unless they give [up their right as] charity. But if he [i.e., the deceased] was from a people at war with you and he was a believer - then [only] the freeing of a believing slave; and if he was from a people with whom you have a treaty - then a compensation payment presented to his family and the freeing of a believing slave. And whoever does not find [one or cannot afford to buy one] - then [instead], a fast for two months consecutively, [seeking] acceptance of repentance from Allāh. And Allāh is ever Knowing and Wise. (Surah An-Nisa, 4:92)

وَجَاءَ فِرْعَوْنُ وَمَن قَبْلَهُ وَالْمُؤْتَفِكَاتُ بِالْخَاطِئَةِ ٩

بِالْخَاطِئَةِ bil-khāṭi-ati · with sin

And there came Pharaoh and those before him and the overturned cities with sin. (Surah Al-Haqqah, 69:9)
