Narated By Abu Huraira RA  : Allah's Apostle PBUH said, "By Him in Whose Hand my life is, it is better for anyone of you to take a rope and cut the wood (from the forest) and carry it over his back and sell it (as a means of earning his living) rather than to ask a person for something and that person may give him or not."
