The main doctrines of the Shī'a are well known; Ibn Babuye, in his book The Reasons for Laws, gives a more popular view of theology.
The imam
‘Alī said: But for us God would not have created Adam, Eve, paradise, hell, heaven and earth. How shall we not be better than the angels? We knew our Lord before they did, our spirits were the first He created, and He made us speak of His unity. Then he created the angels and, when they saw that our spirits were one light, they glorified us; but we praised God that they might know that we too were created creatures. It is said that God created the five, Muḥammad, ‘Alī, Fāṭima, Ḥasan and Ḥusain seven thousand years before the world; they were before the throne. Ḥusain said: We were forms of light, circling round the throne of the Merciful; we taught the angels to praise, laud and magnify. Another expression is: A brilliant light, which was the substance (clay) of ‘Alī, passed before the angels. God created the hearts and bodies of the prophets from the substance of the highest places (‘illiyūn). An imam said: God created us from the highest places and our spirits from something higher; He created the spirits of our followers from the highest places and their bodies from something lower, so they are kin to us and their hearts yearn towards us. Then God created Adam and placed us in his loins; He commanded the angels to bow down to him to honour us. Their prostration was worship of God and respect and obedience to Adam because we were in his loins.
