Expiation for Murdering someone
الشَّهْرُ الْحَرَامُ بِالشَّهْرِ الْحَرَامِ وَالْحُرُمَاتُ قِصَاصٌ ۚ فَمَنِ اعْتَدَىٰ عَلَيْكُمْ فَاعْتَدُوا عَلَيْهِ بِمِثْلِ مَا اعْتَدَىٰ عَلَيْكُمْ ۚ وَاتَّقُوا اللَّهَ وَاعْلَمُوا أَنَّ اللَّهَ مَعَ الْمُتَّقِينَ {194}
The Sacred Month with the sacred Month and the Sacred things are (subject to) retaliation; So the one who assaults upon you, then assault upon him with the like of what he assaulted upon you; and fear Allah and know that Allah is with the fearing ones [2:194]
محمد بن يعقوب: عن علي بن إبراهيم، عن أبيه، و محمد بن إسماعيل، عن الفضل بن شاذان، جميعا، عن ابن أبي عمير، عن معاوية بن عمار، قال
Muhammad Bin Yaqoub, from Ali Bin Ibrahim, from his father, and Muhammad Bin Ismail, from Al Fazal Bin Shazaan, altogether, from Ibn Abu Umeyr, from Muawiya Bin Amaar who said,
سألت أبا عبد الله (عليه السلام) عن رجل قتل رجلا في الحل، ثم دخل الحرم. فقال: «لا يقتل و لا يطعم و لا يسقى و لا يبايع و لا يؤوى حتى يخرج من الحرم فيقام عليه الحد
‘I asked Abu Abdullah-asws about a man who killed a man in the non-sacred area (outside the Harrum), then he entered the Harrum (Sanctuary)’. He-asws said: ‘He would neither be killed, nor fed, nor quenched, nor sold to, nor sheltered, until he exits from the Harrum, so the legal punishment would be established upon him’.
قال: قلت: فما تقول في رجل قتل في الحرم أو سرق؟ قال: «يقام عليه الحد في الحرم، لأنه لم ير للحرم حرمة، و قد قال الله عز و جل: فَمَنِ اعْتَدى عَلَيْكُمْ فَاعْتَدُوا عَلَيْهِ بِمِثْلِ مَا اعْتَدى عَلَيْكُمْ- فقال-: هذا هو في الحرم- فقال- فَلا عُدْوانَ إِلَّا عَلَى الظَّالِمِينَ
He (the narrator said, ‘I said, ‘So what are you-asws saying regarding a man who kills or steals inside the Harrum (Sanctuary)?’ he-asws said: ‘The legal punishment would be applied upon him inside the Harrum, because he did not view the Harrum as sacred, and Allah-azwj Mighty and Majestic has Said: So the one who assaults upon you, then assault upon him with the like of what he assaulted upon you [2:194] – this is inside the Sanctuary – so He-azwj Said: Then there should not be hostility except upon the unjust ones [2:193]’.[1]
