Anas bin Malik (May Allah be pleased with him) reported:
A young man from the tribe of Aslam said, "O Messenger of Allah ﷺ, I wish to fight (in the Cause of Allah) but I do not have anything to equip myself with (for fighting)". He (the Prophet ﷺ) 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, "Messenger of Allah ﷺ sends you his greetings and says that you should give me the equipment that you have provided yourself with." The man said (to his wife or servant): "O so-and-so, give him the equipment I have collected for myself and do not withhold anything from him. By Allah, if you withhold anything from him, we will not be blessed therein".
وعن أنس رضي الله عنه أن فتى من أسلم قال: يا رسول الله إني أريد الغزو وليس معي ما أتجهز به؟ قال:
"ائت فلانا فإنه قد كان تجهز فمرض" فأتاه فقال: إن رسول الله ﷺ يقرئك السلام ويقول: أعطني الذي تجهزت به، فقال: يا فلانة أعطيه الذي تجهزت به، ولا تحبسي منه شيئاً ، فوالله لا تحبسين منه شيئاً فيبارك لك فيه. ((رواه مسلم)).
