Offences for which no Responsibility is Incurred - Section 1
وَعَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِذَا قَاتَلَ أَحَدُكُمْ فَلْيَجْتَنِبِ الْوَجْهَ فَإِنَّ اللَّهَ خَلَقَ آدَمَ عَلَى صُورَتِهِ»
He reported God’s Messenger as saying, “When any of you fights he must avoid the face, for God created Adam in His own image.” (Bukhari and Muslim.)
