عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((مَنْ قَتَلَ قَتِيلًا مِنْ أَهْلِ الذِّمَّةِ لَمْ يَرَحْ رَائِحَةَ الْجَنَّةِ وَإِنَّ رِيحَهَا لَيُوجَدُ مِنْ مَسِيرَةِ أَرْبَعِينَ عَامًا))
Narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: Whoever kills a person from among those with whom there is a treaty, will not smell the fragrance of Paradise, though its fragrance is perceived from a distance of forty years.
