"The late Imam Khomeini (may Allah elevate his station) often cited this example in his lectures: “If an Islamic ruler asks me to hand this cloak of mine over to him, I would obey and say, “With pleasure”. Whenever the Wali al-Faqih sees that the expediency of the Islamic society demands that I should hand over to him my cloak, I have to obey and give it over.” This is the true meaning of wilayat al-faqih."
