Ta'wil of word 'Kullu shay'in' (Everything, all things):
 
"The wise Qur'an is the perfect and complete Book in whose exoteric and esoteric aspects there is explanation of everything (16:89). The magnificent and unique principle which is the treasure of its heart cannot be praised by us human beings and that universal principle full of quintessence (i.e., the pure, highly concentrated essence) of wisdom is: "And We have encompassed everything in a manifest Imam." (36:12). That is, all spiritual and intellectual subtle things of the kingdom of God can be found gathered and enfolded in the manifest Imam, provided someone recognizes himself or herself."
