Sahih Muslim Book 5, Hadith Number 2268.

Chapter : One for whom begging is permissible.

Qais b. Abu Hizam reported: We came to Abu Huraira and he told Allah’s Messenger (may peace be upon him) having said this: By Allah, (it is better) that one among you should go and bring a load of firewood on his back and he should sell it, and the rest of the Hadith was narrated (like the previous one).
