Musnad Abu Ya'la al-Mawsili 245:1

'Abd al-A'la ibn Hammad narrated to us, Wahb ibn Jarir narrated to us, my father narrated to us, he said: I heard Yahya ibn Ayyub narrating from Yazid ibn Abi Habib, from Ja'far ibn Rabi'ah, from 'Abd Allah ibn 'Amir, from Mu'awiyah ibn Abi Sufyan, he said: I heard the Messenger of Allah (may Allah bless him and grant him peace) saying: "I am only a treasurer, and it is Allah who gives. So whoever I give a gift to while I am of good soul regarding it, it is blessed for him in it. And whoever I give a gift to out of greed of soul and intensity of asking, he is like the one who eats and is not satisfied."
