Hadith 211
Ibn Mas'ud reported God’s messenger as saying, “No life is taken unjustly without a portion of its blood being laid at the door of Adam’s first son, because he was the first to introduce murder.” (Bukhari and Muslim). We shall mention the tradition from Mu'awiya, “A section of my people will continue .. .”* in the chapter on the reward of this people, if God will. *Book XXV, Chap. xli. The wording is slightly different.
وَعَنِ ابْنِ مَسْعُودٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَا تُقْتَلُ نَفْسٌ ظُلْمًا إِلَّا كَانَ عَلَى ابْنِ آدَمَ الْأَوَّلِ كِفْلٌ مِنْ دَمِهَا لِأَنَّهُ أَوَّلُ مَنْ سَنَّ الْقَتْلَ» . وَسَنَذْكُرُ حَدِيثَ مُعَاوِيَةَ: «لَا يَزَالُ مِنْ أُمَّتِي» فِي بَابِ ثَوَابِ هَذِهِ الْأُمَّةِ إِنْ شَاءَ الله تَعَالَى
