Bryd bin 'Abdullah بريد بن عبد الله بن أبي · The Book of Zakah

the Messenger of Allah said, when mentioning charity and those who refrain from asking. "The upper hand is better than the lower hand; the upper hand is that which gives and the lower hand is that which asks."

"O Prophet of Allah, I do not have anything but that which Az-Zubair brings to me. Is there any sin on me if I give a small amount of that which he brings to me?" He said: Give whatever you can, and do not withhold what you have, lest Allah withhold provision from you."

"I heard the Messenger of Allah (ﷺ) say: 'Give charity, for there will come a time when a man will walk about with his charity, and the one to whom he wants to give it will say: If you had brought it yesterday I would have accepted it, but today (I have no need of it)."
