(1) باب مَا جَاءَ فِي التَّمَنِّي وَمَنْ تَمَنَّى الشَّهَادَةَ
Narrated Abu Huraira:
I heard Allah's Messenger (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.
