Musnad Abu Ya'la al-Mawsili 117:19

Narrated to us Abd al-Rahman, narrated to us Hammad, from Thabit, from Anas: A young man from Aslam said, "O Messenger of Allah, I desire to go on Jihad, but I do not possess that with which I can equip myself." He said, "Go to such-and-such an Ansari, for he had prepared himself [for Jihad]. Tell him: 'The Messenger of Allah sends you peace and says to you: Give me what you have prepared yourself with.'" So he went to him and said [it]. The man said—I believe he was referring to his wife—"Do not hide anything from him, for by Allah, if you do not hide anything from him, it will be blessed for us."
