Anybody who equips a warrior (going to fight) in the way of Allah (is like one who actually) fights. And anybody who looks well after his family in his absence (is also like one who actually) fights.
Sahih Muslim Book 33, Hadith 198
← Previous Hadith Messenger of Allah, I wish to fight (in the way of Allah) but I don't have anything to equip myself with for fighting. He (the Holy Prophet) said: Go to so and so, for he had equipped himself (for fighting) but he fell ill. So, he (the young man) went to him and said: The Messenger of Allah (ﷺ) sends you his greetings and says that you should give me the equipage that you have provided yourself with. The man said (to his wife or maidservant): So and so, give him the equipage I have collected for myself and do not withhold anything from him. Do not withhold anything from him so that you may be blessed therein.
