Narrated Abu Sa`id Al-Khudri
Some Ansari persons asked for (something) from Allah's Messenger (ﷺ) (p.b.u.h) and he gave them. They again asked him for (something) and he again gave them. And then they asked him and he gave them again till all that was with him finished. And then he said "If I had anything. I would not keep it away from you. (Remember) Whoever abstains from asking others, Allah will make him contented, and whoever tries to make himself self-sufficient, Allah will make him self-sufficient. And whoever remains patient, Allah will make him patient. Nobody can be given a blessing better and greater than patience."
Narrated Abu Huraira
Allah's Messenger (ﷺ) 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."
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."
Narrated `Urwa bin Az-Zubair and Sa`id bin Al-Musaiyab
Hakim bin Hizam said, "(Once) I asked Allah's Messenger (ﷺ) (for something) and he gave it to me. Again I asked and he gave (it to me). Again I asked and he gave (it to me). And then he said, "O Hakim! This property is like a sweet fresh fruit; whoever takes it without greediness, he is blessed in it, and whoever takes it with greediness, he is not blessed in it, and he is like a person who eats but is never satisfied; and the upper (giving) hand is better than the lower (receiving) hand." Hakim added, "I said to Allah's Messenger (ﷺ), 'By Him (Allah) Who sent you with the Truth, I shall never accept anything from anybody after you, till I leave this world.' " Then Abu Bakr (during his caliphate) called Hakim to give him his share from the war booty (like the other companions of the Prophet (ﷺ) ), he refused to accept anything. Then `Umar (during his caliphate) called him to give him his share but he refused. On that `Umar said, "O Muslims! I would like you to witness that I offered Hakim his share from this booty and he refused to take it." So Hakim never took anything from anybody after the Prophet (ﷺ) till he died.
