The Key to the House of Happiness and the publication of the Guardianship of Knowledge and Will is one of the works of Imam Ibn Qayyim al-Jawziyyah. He opened it with an introduction to the wisdom and secrets in expelling our father Adam from Paradise. Then he moved on to talk about knowledge and will and explained that these two principles are the means by which the human soul is perfected and achieves what God intended for it in terms of servitude. She deserves the covenant that God made for her to enter Paradise after God's mercy.
