A person said to a certain Shaykh, “Advise me'”, and he said to him, “Be a king in this world and you will be a king in the next”. When he said, “How might I do that?” the shaykh answered,
Renounce this world and you will be a king in the next
He meant, detach your needs and your passions from this world, for kingship lies in being free and able to dispense with everything.
Imam Ghazali (Rahimahullah)
