وَ رُوِيَ عَنْ حَنَانِ بْنِ سَدِيرٍ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ: فِي قَوْلِ اَللَّهِ عَزَّ وَ جَلَّ أَنَّهُ مَنْ قَتَلَ نَفْساً بِغَيْرِ نَفْسٍ أَوْ فَسٰادٍ فِي اَلْأَرْضِ فَكَأَنَّمٰا قَتَلَ اَلنّٰاسَ جَمِيعاً قَالَ "هُوَ وَادٍ فِي جَهَنَّمَ لَوْ قَتَلَ اَلنَّاسَ جَمِيعاً كَانَ فِيهِ وَ لَوْ قَتَلَ نَفْساً وَاحِدَةً كَانَ فِيهِ".
It is narrated from Hanan ibn Sadir from Abu Abdullah (a.s) regarding the saying of Allah (swt), the Almighty and Majestic: "Whoever kills a soul without [the soul having killed] another soul or [without causing] corruption on the earth, it is as if he had killed all mankind" (Surah Al-Ma'idah 5:32). Imam (a.s) said: "It is a valley in Hell; if a person were to kill all of mankind, he would be in it, and if he were to kill just one soul, he would still be in it."
