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.
