Riyad as-Salihin 1308
Anas (May Allah be pleased with him) reported:
A young man from the Aslam tribe said: "O Messenger of Allah! I would very much like to fight in the way of Allah but I do not have anything with which to equip myself for fighting." The Messenger of Allah (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: "The Messenger of Allah (ﷺ) sends you his greetings and says that you should hand over to me the equipment that you have procured." The man said to his wife: "Give him the equipment which I have collected for myself and do not withhold anything from him. By Allah! Allah won't bless something you withheld (in this respect)." [Muslim] .
وعن أنس رضي الله عنه أن فتى من أسلم قال‏:‏ يا رسول الله إني أريد الغزو وليس معي ما أتجهز به، قال‏:‏ ‏"‏ائت فلانًا، قد كان تجهز فمرض فأتاه فقال‏:‏ إن رسول الله صلى الله عليه وسلم يقرئك السلام ويقول‏:‏ أعطني الذي تجهزت به قال‏:‏ يا فلانة أعطيه، الذي كنت تجهزت به ولاتحبسي منه شيئًا فوالله لا تحبسي منه شيئًا فيبارك لك  فيه ‏(‏‏(‏رواه مسلم‏)‏‏)‏‏.‏
