Allah has undertaken to look after the affairs of one who goes out to fight in His way believing in Him and affirming the truth of His Apostles. He is committed to His care that Re will either admit him to Paradise or bring him back to his home from where he set out with a reward or (his share of) booty. By the Being in Whose Hand is the life of Muhammad. If a person gets wounded in the way of Allah, he will come on the Day of Judgment with his wound in the same condition as it was when it was first inflicted; its colour being the colour of blood but its smell will be the smell of musk. By, the Being in Whose Hand is Muhammad's life, if it were not to be too hard upon the Muslime. I would not lag behind any expedition which is going to fight in the cause of Allah. But I do not have abundant means to provide them (the Mujahids) with riding beasts, nor have they (i. e. all of them) abundant means (to provide themselves with all the means of Jihad) so that they could he left behind. By the Being in Whose Hand is Muhammad's life, I love to fight in the way of Allah and be killed, to fight and again be killed and to fight again and be killed.  

قَالَ رَسُولُ اللَّهِ ﷺ تَضَمَّنَ اللَّهُ لِمَنْ خَرَجَ فِي سَبِيلِهِ لاَ يُخْرِجُهُ إِلاَّ جِهَادًا فِي سَبِيلِي وَإِيمَانًا بِي وَتَصْدِيقًا بِرُسُلِي فَهُوَ عَلَىَّ ضَامِنٌ أَنْ أُدْخِلَهُ الْجَنَّةَ أَوْ أَرْجِعَهُ إِلَى مَسْكَنِهِ الَّذِي خَرَجَ مِنْهُ نَائِلاً مَا نَالَ مِنْ أَجْرٍ أَوْ غَنِيمَةٍ وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ مَا مِنْ كَلْمٍ يُكْلَمُ فِي سَبِيلِ اللَّهِ إِلاَّ جَاءَ يَوْمَ الْقِيَامَةِ كَهَيْئَتِهِ حِينَ كُلِمَ لَوْنُهُ لَوْنُ دَمٍ وَرِيحُهُ مِسْكٌ وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ لَوْلاَ أَنْ يَشُقَّ عَلَى الْمُسْلِمِينَ مَا قَعَدْتُ خِلاَفَ سَرِيَّةٍ تَغْزُو فِي سَبِيلِ اللَّهِ أَبَدًا وَلَكِنْ لاَ أَجِدُ سَعَةً فَأَحْمِلَهُمْ وَلاَ يَجِدُونَ سَعَةً وَيَشُقُّ عَلَيْهِمْ أَنْ يَتَخَلَّفُوا عَنِّي وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ لَوَدِدْتُ أَنِّي أَغْزُو فِي سَبِيلِ اللَّهِ فَأُقْتَلُ ثُمَّ أَغْزُو فَأُقْتَلُ ثُمَّ أَغْزُو فَأُقْتَلُ  

“Allah has prepared (reward) for those who go out (to fight) in His cause: ‘And do not go out except (to fight) for Jihad in My cause, out of faith in Me and belief in My Messengers, but he has a guarantee from Me that I will admit him to Paradise, or I will return him to his dwelling from which he set out, with the reward that he attained, or the spoils that he acquired.’ Then he said: ‘By the One in Whose Hand is my soul, were it not that it would be too difficult for the Muslims, I would never have stayed behind from any expedition that went out in the cause of Allah. But I could not find the resources to give them mounts and they could not find the resources to follow me, nor would they be pleased to stay behind if I went. By the One in Whose Hand is the soul of Muhammad, I wish I could fight in the cause of Allah and be killed, then fight and be killed, then fight and be killed.’”  

قَالَ رَسُولُ اللَّهِ ﷺ أَعَدَّ اللَّهُ لِمَنْ خَرَجَ فِي سَبِيلِهِ لاَ يُخْرِجُهُ إِلاَّ جِهَادٌ فِي سَبِيلِي وَإِيمَانٌ بِي وَتَصْدِيقٌ بِرُسُلِي فَهُوَ عَلَىَّ ضَامِنٌ أَنْ أُدْخِلَهُ الْجَنَّةَ أَوْ أَرْجِعَهُ إِلَى مَسْكَنِهِ الَّذِي خَرَجَ مِنْهُ نَائِلاً مَا نَالَ مِنْ أَجْرٍ أَوْ غَنِيمَةٍ ثُمَّ قَالَ وَالَّذِي نَفْسِي بِيَدِهِ لَوْلاَ أَنْ أَشُقَّ عَلَى الْمُسْلِمِينَ مَا قَعَدْتُ خِلاَفَ سَرِيَّةٍ تَخْرُجُ فِي سَبِيلِ اللَّهِ أَبَدًا وَلَكِنْ لاَ أَجِدُ سَعَةً فَأَحْمِلَهُمْ وَلاَ يَجِدُونَ سَعَةً فَيَتَّبِعُونِي وَلاَ تَطِيبُ أَنْفُسُهُمْ فَيَتَخَلَّفُونَ بَعْدِي وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ لَوَدِدْتُ أَنْ أَغْزُوَ فِي سَبِيلِ اللَّهِ فَأُقْتَلَ ثُمَّ أَغْزُوَ فَأُقْتَلَ ثُمَّ أَغْزُوَ فَأُقْتَلَ

"أَعَدَّ الله لمنْ خرجَ في سَبِيله، لَا يُخْرِجُهُ إلا الجهَادُ في سَبِيلي، وإيمانٌ وتصديقٌ بِرُسلى، فهو عليَّ ضامِنٌ أَنْ أدْخِلَهُ الجنَّةَ، أو أَرْجِعَهُ إلى مَسْكَنه الَّذي خرج مِنْهُ نائلًا ما نال مِنْ أَجْرٍ أَوْ غَنيمةٍ، والَّذى نَفْسي بيِدَهِ لَوْلَا أنْ أَشُقَّ عَلَى الْمُسْلِميَن مَا قَعَدتْ خِلافَ سَرِيَّةٍ تَخْرُجُ في سبيل الله أبدًا، ولكنْ لا أجدُ سعةً فأحْملَهُمْ، ولا يجدُونَ سعةً فيتبعوني، وَلَا تَطِيبُ أنفسهم فيتخلَّفون بَعْدِي، والَّذى نفسُ محمد بيَدِه لَوَدِدْتُ أنْ أغزوَ في سبيل الله، فأُقْتَل، ثم أَغْزوَ فأُقْتلَ، ثُمَّ أَغْزوَ فأُقتلَ" .
