Sahih Muslim Book - 32, Hadith - 4600

حَدَّثَنَا أَبُو كُرَيْبٍ حَدَّثَنَا ابْنُ نُمَيْرٍ عَنْ هِشَامٍ أَخْبَرَنِى أَبِى عَنْ عَائِشَةَ أَنَّ سَعْدًا قَالَ وَتَحَجَّرَ كَلْمُهُ لِلْبُرْءِ فَقَالَ اللَّهُمَّ إِنَّكَ تَعْلَمُ أَنْ لَيْسَ أَحَدٌ أَحَبَّ إِلَىَّ أَنْ أُجَاهِدَ فِيكَ مِنْ قَوْمٍ كَذَّبُوا رَسُولَكَ -صلى الله عليه وسلم- وَأَخْرَجُوهُ اللَّهُمَّ فَإِنْ كَانَ بَقِىَ مِنْ حَرْبِ قُرَيْشٍ شَىْءٌ فَأَبْقِنِى أُجَاهِدْهُمْ فِيكَ اللَّهُمَّ فَإِنِّى أَظُنُّ أَنَّكَ قَدْ وَضَعْتَ الْحَرْبَ بَيْنَنَا وَبَيْنَهُمْ فَإِنْ كُنْتَ وَضَعْتَ الْحَرْبَ بَيْنَنَا وَبَيْنَهُمْ فَافْجُرْهَا وَاجْعَلْ مَوْتِى فِيهَا. فَانْفَجَرَتْ مِنْ لَبَّتِهِ فَلَمْ يَرُعْهُمْ - وَفِى الْمَسْجِدِ مَعَهُ خَيْمَةٌ مِنْ بَنِى غِفَارٍ - إِلاَّ وَالدَّمُ يَسِيلُ إِلَيْهِمْ فَقَالُوا يَا أَهْلَ الْخَيْمَةِ مَا هَذَا الَّذِى يَأْتِينَا مِنْ قِبَلِكُمْ فَإِذَا سَعْدٌ جُرْحُهُ يَغِذُّ دَمًا فَمَاتَ مِنْهَا.

It was narrated from 'Aishah that when Sa'd's wound became dry and was about to heal, he said: O Allah, You know that there is nothing dearer to me than striving in Jihad for Your sake, against people who disbelieved in Your Messenger (s.a.w) and expelled him. O Allah, if any war against Quraish remains, keep me alive so that I may fight in Jihad against them for Your sake. O Allah, I think that You have ended the war between us and them. If You have ended the war between us and them, then open my wound so that my death may be due to that. Then he began to bleed from the base of his throat, and the people - there were some tents of Banu Ghifar in the Masjid with him - were startled when they saw the blood flowing towards them. Then they said: O people of the tents, what is this that is coming from you? Then they saw that Sa'd's wound was pouring with blood and he died of that.
