ثُمَّ أَنتُمْ هَٰؤُلَاءِ تَقْتُلُونَ أَنفُسَكُمْ وَتُخْرِجُونَ فَرِيقًا مِّنكُم مِّن دِيَارِهِمْ تَظَاهَرُونَ عَلَيْهِم بِالْإِثْمِ وَالْعُدْوَانِ وَإِن يَأْتُوكُمْ أُسَارَىٰ تُفَادُوهُمْ وَهُوَ مُحَرَّمٌ عَلَيْكُمْ إِخْرَاجُهُمْ أَفَتُؤْمِنُونَ بِبَعْضِ الْكِتَابِ وَتَكْفُرُونَ بِبَعْضٍ فَمَا جَزَاءُ مَن يَفْعَلُ ذَٰلِكَ مِنكُمْ إِلَّا خِزْيٌ فِي الْحَيَاةِ الدُّنْيَا وَيَوْمَ الْقِيَامَةِ يُرَدُّونَ إِلَىٰ أَشَدِّ الْعَذَابِ وَمَا اللَّهُ بِغَافِلٍ عَمَّا تَعْمَلُونَ ٨٥

بِالْإِثْمِ bil-ith'mi · in sin

Then, you are those [same ones who are] killing one another and evicting a party of your people from their homes, cooperating against them in sin and aggression. And if they come to you as captives, you ransom them, although their eviction was forbidden to you. So do you believe in part of the Scripture and disbelieve in part? Then what is the recompense for those who do that among you except disgrace in worldly life; and on the Day of Resurrection they will be sent back to the severest of punishment. And Allāh is not unaware of what you do. (Surah Al-Baqarah, 2:85)

إِنَّمَا حَرَّمَ عَلَيْكُمُ الْمَيْتَةَ وَالدَّمَ وَلَحْمَ الْخِنزِيرِ وَمَا أُهِلَّ بِهِ لِغَيْرِ اللَّهِ فَمَنِ اضْطُرَّ غَيْرَ بَاغٍ وَلَا عَادٍ فَلَا إِثْمَ عَلَيْهِ إِنَّ اللَّهَ غَفُورٌ رَّحِيمٌ ١٧٣

إِثْمَ ith'ma · sin

He has only forbidden to you dead animals, blood, the flesh of swine, and that which has been dedicated to other than Allāh. But whoever is forced [by necessity], neither desiring [it] nor transgressing [its limit], there is no sin upon him. Indeed, Allāh is Forgiving and Merciful. (Surah Al-Baqarah, 2:173)

يَمْحَقُ اللَّهُ الرِّبَا وَيُرْبِي الصَّدَقَاتِ وَاللَّهُ لَا يُحِبُّ كُلَّ كَفَّارٍ أَثِيمٍ ٢٧٦

أَثِيمٍ athīmin · sinner

Allāh destroys interest and gives increase for charities. And Allāh does not like every sinning disbeliever. (Surah Al-Baqarah, 2:276)

وَإِن كُنتُمْ عَلَىٰ سَفَرٍ وَلَمْ تَجِدُوا كَاتِبًا فَرِهَانٌ مَّقْبُوضَةٌ فَإِنْ أَمِنَ بَعْضُكُم بَعْضًا فَلْيُؤَدِّ الَّذِي اؤْتُمِنَ أَمَانَتَهُ وَلْيَتَّقِ اللَّهَ رَبَّهُ وَلَا تَكْتُمُوا الشَّهَادَةَ وَمَن يَكْتُمْهَا فَإِنَّهُ آثِمٌ قَلْبُهُ وَاللَّهُ بِمَا تَعْمَلُونَ عَلِيمٌ ٢٨٣

آثِمٌ āthimun · (is) sinful

And if you are on a journey and cannot find a scribe, then a security deposit [should be] taken. And if one of you entrusts another, then let him who is entrusted discharge his trust [faithfully] and let him fear Allāh, his Lord. And do not conceal testimony, for whoever conceals it - his heart is indeed sinful, and Allāh is Knowing of what you do. (Surah Al-Baqarah, 2:283)

يَتَنَازَعُونَ فِيهَا كَأْسًا لَّا لَغْوٌ فِيهَا وَلَا تَأْثِيمٌ ٢٣

تَأْثِيمٌ tathīmun · sin

They will exchange with one another a cup [of wine] wherein [results] no ill speech or commission of sin. (Surah At-Tur, 52:23)

وَالَّذِينَ لَا يَدْعُونَ مَعَ اللَّهِ إِلَٰهًا آخَرَ وَلَا يَقْتُلُونَ النَّفْسَ الَّتِي حَرَّمَ اللَّهُ إِلَّا بِالْحَقِّ وَلَا يَزْنُونَ وَمَن يَفْعَلْ ذَٰلِكَ يَلْقَ أَثَامًا ٦٨

أَثَامًا athāman · a penalty

And those who do not invoke with Allāh another deity or kill the soul which Allāh has forbidden [to be killed], except by right, and do not commit unlawful sexual intercourse. And whoever should do that will meet a penalty. (Surah Al-Furqan, 25:68)
