SECURITY H 221 "A believer continues to be secure in his faith so long as he does not shed blood unjustly." R 221 Bukhari with a chain up to ibn Omar who related: The Messenger of Allah, praise and peace be upon him, said this.
220- وعن ابن عمر رضي الله عنهما ، قَالَ : قَالَ رَسُول الله صلى الله عليه وآله وسلم : "لَنْ يَزَالَ المُؤْمِنُ في فُسْحَةٍ مِنْ دِينهِ مَا لَمْ يُصِبْ دَماً حَرَاماً" رواه البخاري .
