Halakhah su Salmi 74:21

It is forbidden to turn away a poor person, empty handed, even if you give him only a dried fig [a mere pittance], as it is said: "Let not the oppressed turn back in disgrace."²²Psalms 74:21. And if you have nothing to give him, console him with words. It is forbidden to scold a poor person or to raise your voice to him in a shout, because he is brokenhearted and humbled, as it is said: "A heart that is broken and humbled God does not despise."²³Psalms 51:19. Woe is to him who embarrasses the poor. Rather act towards him like a father, both in [feelings of] compassion and with words, as it is said: "I was a father to the poor."²⁴Job 29:16.

If the poor man stretches out his hand and he has nothing to give him, he should not scold and raise his voice to him, but should speak gently to him and show him his goodness of heart; namely, that he wishes to give him something but cannot. RMI.—It is forbidden to turn away a poor man entirely empty-handed. Let him give something, if only a fig, for it is written, "Oh, let not the oppressed return ashamed."¹Psalms 74:21.
