“Whoever kills a Mu'ahid who has the protection of Allah and the protection of his Messenger, will not smell the fragrance of Paradise, even though its fragrance may be detected from a distance of Seventy years.” (Using translation from Ibn Mājah 2687)
عَنِ النَّبِيِّ ﷺ قَالَ «أَلَا مَنْ قَتَلَ مُعَاهَدًا لَهُ ذِمَّةُ اللَّهِ وَذِمَّةُ رَسُولِهِ فَقَدْ خَفَرَ ذِمَّةَ اللَّهِ وَلَا يَرَحْ رِيحَ الْجَنَّةِ وَإِنَّ رِيحَهَا لَيُوجَدُ مِنْ مَسِيرَةِ سَبْعِينَ خَرِيفًا» على شرط مسلم
