As-Salaam alaikum,
The Noble Messenger of Allah, Sallallahu alaihi Wasallam, said: "He who humbles himself before Allah, Allah elevates [in degree]."
He who increases himself in humility and abasement, Allah grants more exalted state. The fuqara, therefore, get high station from their Lord through their abasement.

Abu Sa'eed al-Khudri, may Allah be pleased with him, related that the Messenger of Allah, Sallallahu alaihi Wasallam, "used to feed his camel, sweep his house, mend his sandals, patch his clothes, milk [his] sheep, eat with his servant and help him grind, when he [the servant] got tired. He was not embarrassed to carry his goods from the bazaar to his family. He would shake hands with both the rich and the poor; he was the first to greet people; he would not scorn any meal of which he was invited to partake, even if this was unripe and dry dates.
He made do with free supplies [of provision], he was gentle of character, generous of nature, pleasant of company; his face was cheerful, he smiled much, without laughing and showed [his] sadness without frowning; he was humble without being self-effacing, generous without being extravagant; his heart was gentle, he was compassionate to every Muslim; he would never eat his fill and he would never stretch his hand to a thing that he desired."...Sallallahu alaihi Wasallam...
