Bukhari

Narrated Abu Sa`id: Some people from the Ansar asked Allah's Apostle (to give them something) and he gave to everyone of them, who asked him, until all that he had was finished. When everything was finished and he had spent all that was in his hand, he said to them, '"(Know) that if I have any wealth, I will not withhold it from you (to keep for somebody else); And (know) that he who refrains from begging others (or doing prohibited deeds), Allah will make him contented and not in need of others; and he who remains patient, Allah will bestow patience upon him, and he who is satisfied with what he has, Allah will make him self-sufficient. And there is no gift better and vast (you may be given) than patience."

And Allah the Exalted has said: "Indeed, those who are patient will be given their reward without account." And ‘Umar (may Allah be pleased with him) said: "We have found the best life in patience."

Narrated Al-Mughira bin Shu`ba: The Prophet used to pray so much that his feet used to become edematous or swollen, and when he was asked as to why he prays so much, he would say, "Shall I not be a thankful slave (to Allah)?"
