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".

[Muslim].

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)).
