It was
narrated from Abu Umamah that the Prophet (ﷺ) said: “Whoever
does
not fight, or equip a fighter, or stay behind to look after a
fighter’s family, Allah will strike him with a calamity before the
Day
of Resurrectio…
It was
narrated from Abu Hurairah that the Messenger of Allah (ﷺ)
said:
“Whoever meets Allah with no mark on him (as a result of
fighting)
in His cause, he will meet Him with a deficiency.”
