It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Whoever is struck by a need and brings it before people, his poverty will not be relieved; and whoever brings it before Allah, Allah will soon make him self-sufficient, either with a reward that comes later or with sufficiency that comes soon."
