It is narrated from Hazrat Ibn Abi Laila that a beggar came to Hazrat Abu Dharr, so he gave him something. People said to him, "Why did you give him (something) even though he is well-off?" He replied, "He is a beggar, and every beggar has a right. And on the Day of Resurrection, they will surely wish (that they had not begged). Indeed, in their hands (on the Day of Resurrection) there will be a hot stone."
