عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ لَوَدِدْتُ أَنْ أُقَاتِلَ فِي سَبِيلِ اللَّهِ فَأُقْتَلَ ثُمَّ أُحْيَا ثُمَّ أُقْتَلَ ثُمَّ أُحْيَا ثُمَّ أُقْتَلَ ثُمَّ أُحْيَا ثُمَّ أُقْتَلَ وَلَوْلَا أَنْ أَشُقَّ عَلَى الْمُؤْمِنِينَ مَا تَخَلَّفْتُ خَلْفَ سَرِيَّةٍ تَخْرُجُ أَوْ تَغْزُو فِي سَبِيلِ اللَّهِ وَلَكِنْ لَا أَجِدُ سَعَةً فَأَحْمِلَهُمْ وَلَا يَجِدُونَ سَعَةً فَيَتَّبِعُونِي وَلَا تَطِيبُ أَنْفُسُهُمْ أَنْ يَتَخَلَّفُوا بَعْدِي أَوْ يَقْعُدُوا بَعْدِي
It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: By Him in Whose hand is the life of Muhammad (peace and blessings be upon him)! I wish to fight in the way of Allah, then be martyred, then be brought back to life and then be martyred again, then be brought back to life and then be martyred again, then be brought back to life and then be martyred again. And if I did not consider it hard upon the believers, I would never stay behind from any army that fights in the way of Allah, but I do not have enough means to provide them with mounts, and they also do not have enough means to prepare themselves and go with me, and their souls do not allow them to stay behind from me.
