Encouraging Livelihood by (working with) Hands and Abstaining from Begging

Riyad-us-Saliheen 540
Abu Hurairah (May Allah be pleased with him) reported: Messenger of Allah (PBUH) said, "It is better for anyone of you to carry a bundle of wood on his back and sell it than to beg of someone whether he gives him or refuses."
