Narrated Hubshi ibn Junadah:
Allah’s Messenger (peace be upon him) said, “Begging is not allowable to a rich man, or to one who has strength and is sound in limb, but only to one who is in grinding poverty or is seriously in debt. If anyone begs to increase thereby his property, it will appear as laceration on his face on the Day of Resurrection and as heated stones which he will eat from Jahannam. So let him who wishes ask little, and let him who wishes ask much.”
Tirmidhi transmitted it. [Tirmidhi]
