Sahih al-Bukhari 1471
Narrated 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."
حَدَّثَنَا مُوسَى، حَدَّثَنَا وُهَيْبٌ، حَدَّثَنَا هِشَامٌ، عَنْ أَبِيهِ، عَنِ الزُّبَيْرِ بْنِ الْعَوَّامِ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏
"‏ لأَنْ يَأْخُذَ أَحَدُكُمْ حَبْلَهُ فَيَأْتِيَ بِحُزْمَةِ الْحَطَبِ عَلَى ظَهْرِهِ فَيَبِيعَهَا فَيَكُفَّ اللَّهُ بِهَا وَجْهَهُ، خَيْرٌ لَهُ مِنْ أَنْ يَسْأَلَ النَّاسَ أَعْطَوْهُ أَوْ مَنَعُوهُ ‏"‏‏.‏
