Sayyiduna Abu Maryam al-Azdi (may Allah be pleased with him), who was a Companion of the Messenger of Allah (peace and blessings be upon him), said: I heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever is put in charge of any affair of the Muslims and shuts himself away from them at the time of their need, their want and their poverty, Allah Almighty will shut Himself away from him on the Day of Resurrection at the time of his necessity, his need, his poverty and his want."
