Musnad Abu Ya'la al-Mawsili 129:148

On the authority of Anas bin Malik, he said: When [the verses] were revealed: "Never will you attain the good [reward] until you spend [in the way of Allah] from that which you love," and "Who is it that would loan Allah a goodly loan?" Abu Talha said: "O Messenger of Allah, my garden which is in such-and-such a place is for Allah. And if I were able to keep it secret, I would not have made it public." The Messenger of Allah (ﷺ) said: "Place it among your relatives," or he said: "Among your kin."
