Sahih Bukhari Volume 2, Book 24, Hadith Number 550.

Narated By Az-Zubair bin Al’Awwam : The Prophet (p.b.u.h) said, “It is better for anyone of you to take a rope (and cut) and bring a bundle of wood (from the forest) over his back and sell it and Allah will save his face (from the Hell-Fire) because of that, rather than to ask the people who may give him or not.”
