I heard Messenger of Allah ﷺ saying, "By Him in Whose Hands my life is! Were it not for some men who dislike to be left behind and for whom I do not have means of conveyance, I would not stay away (from any Holy Battle). I would love to be martyred in Allah's Cause and come to life and then get, martyred and then come to life and then get martyred and then get resurrected and then get martyred.  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ وَالَّذِي نَفْسِي بِيَدِهِ لَوْلاَ أَنَّ رِجَالاً يَكْرَهُونَ أَنْ يَتَخَلَّفُوا بَعْدِي وَلاَ أَجِدُ مَا أَحْمِلُهُمْ مَا تَخَلَّفْتُ لَوَدِدْتُ أَنِّي أُقْتَلُ فِي سَبِيلِ اللَّهِ ثُمَّ أُحْيَا ثُمَّ أُقْتَلُ ثُمَّ أُحْيَا ثُمَّ أُقْتَلُ ثُمَّ أُحْيَا ثُمَّ أُقْتَلُ  

Abu Huraira said, Messenger of Allah ﷺ said, "By Him in Whose Hand my life is, I would love to fight in Allah's Cause and then get martyred and then resurrected (come to life) and then get martyred and then resurrected (come to life) and then get martyred, and then resurrected (come to life) and then get martyred and then resurrected (come to life)." Abu Huraira used to repeat those words three times and I testify to it with Allah's Oath.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ وَالَّذِي نَفْسِي بِيَدِهِ وَدِدْتُ أَنِّي لأُقَاتِلُ فِي سَبِيلِ اللَّهِ فَأُقْتَلُ ثُمَّ أُحْيَا ثُمَّ أُقْتَلُ ثُمَّ أُحْيَا ثُمَّ أُقْتَلُ ثُمَّ أُحْيَا ثُمَّ أُقْتَلُ ثُمَّ أُحْيَا فَكَانَ أَبُو هُرَيْرَةَ يَقُولُهُنَّ ثَلاَثًا أَشْهَدُ بِاللَّهِ
