Military Expeditions led by the Prophet (pbuh) (Al-Maghaazi)
حَدَّثَنِي مَخْلَدُ بْنُ مَالِكٍ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ الأُمَوِيُّ، حَدَّثَنَا ابْنُ جُرَيْجٍ، عَنْ عَمْرِو بْنِ دِينَارٍ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ قَالَ اشْتَدَّ غَضَبُ اللَّهِ عَلَى مَنْ قَتَلَهُ النَّبِيُّ صلى الله عليه وسلم فِي سَبِيلِ اللَّهِ، اشْتَدَّ غَضَبُ اللَّهِ عَلَى قَوْمٍ دَمَّوْا وَجْهَ نَبِيِّ اللَّهِ صلى الله عليه وسلم.Narrated Ibn `Abbas:Allah's Wrath became severe on him whom the Prophet (ﷺ) had killed in Allah's Cause. Allah's Wrath became severe on the people who caused the face of Allah's Prophet to bleed
