Narrated Umm Bujayd:
She took the oath of allegiance to the Messenger of Allah (ﷺ)and said to him: Messenger of Allah, a poor man stands at my door, but I find nothing to give him. The Messenger of Allah (ﷺ) said to her: If you do not find anything to give him, put something in his hand, even though it should be a burnt hoof.
