وَإِذَا اسْتُشْهِدَ الْجُنُبُ: غُسِّلَ عِنْدَ أَبِي حَنِيفَةَ، وَكَذَلِكَ الصَّبِيُّ،
Translation: If a person in janabah is martyred, Imam Abu Hanifa says the body is washed; the same rule applies to a minor.
Junub means a person in major ritual impurity. Imam Abu Hanifa preserves the washing requirement in that case.
Sabi means a minor; in his view a minor martyr is also washed. The reasons given for the two classes differ, so the bare label “martyr” does not erase the subdivisions.
