Let one of you not consider any good to be insignificant
Narrated Abu Dharr, may Allah be pleased with him, that the Messenger of Allah, may the peace and blessings of Allah be upon him, said: "Let one of you not consider any good to be insignificant. If he has nothing, then let him meet his brother with a smiling face. If you buy some meat or cook something in a pot, then increase its broth, and serve some of it to your neighbor."
The similitude of the Prophet`s generosity is like the uncontrollable wind that spread goodness wherever it is. He does not ever reject a beggar or leave a needy unless he helps him. This is one of his traits, may the peace and blessings of Allah be upon him, he did not pretend to act generously rather it was his natural tendency. He is the honorable and the son of the honorable, he is matchless in this field.
His critical situation did not prevent him from favoring his companions over himself with what he needs, so that his altruism is proverbial, to the extent that history did not mention the like of his altruism.
This is why he recommended to his companions that they follow him in all the good deeds, everyone according to his capacity without belittling his effort; without saying to oneself: how will my deed avail me? I just offer him a morsel that do not satisfy his hunger, or a piece of cloth that does not cover his body. He who follows such a way will refrain from spending at all., his soul will be familiar with stinginess of what he has, and Satan will surely tempt him to take and to refuse to give.
