Ibn ‘Umar reported God’s Messenger as saying, “A believer will continue to find ample scope in his religion as long as he does not kill anyone unlawfully.” Bukhari transmitted it.

وَعَنِ ابْنِ عُمَرَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَنْ يَزَالَ الْمُؤْمِنُ فِي فُسْحَةٍ مِنْ دِينِهِ مَا لَمْ يُصِبْ دَمًا حَرَامًا» . رَوَاهُ البُخَارِيّ
