Halakha Ayub 29:16: Mishneh Torah, Gifts to the Poor & Kitzur Shulchan Arukh

If a poor person asks of you [to give him something], and you do not have anything in your possession to give to him, comfort him with words.¹⁸⁴See Leviticus Rabbah 34:15 as well as Babylonian Talmud Bava Batra 9b. It is forbidden to speak harshly to a poor person or to raise your voice in a shout, for his heart is broken and crushed. Thus it says in Scripture, (Psalms 51:19) God, You will not despise a contrite and crushed heart. And it says, (Isaiah 57:15) Reviving the spirits of the lowly, reviving the hearts of the contrite. And woe to anyone who shames a poor person! Woe to him! Rather, let him be like a father to him, in compassion and in words, as it is said, (Job 29:15) I was a father to the needy.

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.
