´It was narrated from Abu Bujaid Al-Ansari from his grandmother that the Messenger of Allah said:` "Respond to the one who asks even with a sheep's foot." According to the narration of Harun: "With a sheep's burned foot."
Explanation & Benefits
Hafiz Muhammad Ameen
The purpose is emphasis, and this ruling applies when the one asking is deserving and the one being asked has the means. Otherwise, giving to professional beggars (provided it is known) may fall under the category of sin, because in this way begging is encouraged, whereas Islam has strictly prohibited it.

Hafiz Muhammad Ameen
The questioner should not be sent away from the door empty-handed. Allah Ta'ala knows best who is truly deserving and who is not, except in the case where it is known that the person is a professional beggar and is not genuinely in need. (Also see, Hadith: 2566)

1:
There is hyperbole in this;
the meaning is that do not turn the beggar away empty-handed—give him whatever is available.

Shaykh Umar Farooq Saeedi
1667. Commentary: The meaning is that one should certainly give something to the beggar; do not send him away empty-handed. However, this ruling does not apply to professional habitual beggars. Giving to professional beggars encourages the profession of begging, which is a crime. Nevertheless, if it is not certain that someone is a professional beggar, then one should assist him according to one's ability.
