Riyad as-Salihin

Ibn Mas'ud (May Allah be pleased with him) reported: Messenger of Allah (ﷺ) said, "He who suffers poverty and seeks relief from people, he will not be relieved; but he who seeks relief from Allah Alone, he will be relieved sooner or later."

[Abu Dawud and At-Tirmidhi, who classified it as Hadith Hasan].
