Read the English translation first, with the original Arabic directly underneath.
Narrated Al-A'raj:
Abu Huraira said, Allah's Messenger (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.
وَالَّذِي نَفْسِي بِيَدِهِ وَدِدْتُ أَنِّي لأُقَاتِلُ فِي سَبِيلِ اللَّهِ فَأُقْتَلُ ثُمَّ أُحْيَا ثُمَّ أُقْتَلُ، ثُمَّ أُحْيَا، ثُمَّ أُقْتَلُ، ثُمَّ أُحْيَا، ثُمَّ أُقْتَلُ، ثُمَّ أُحْيَا
