Indeed, Allah (swt) created Adam from clay, then created Eve from him, and then placed her in the space between his legs. This was because the woman follows [temporally, in creation] from the man. Then Adam said: “O Lord, what is this beautiful creation, which you have made sweet for me to be close to, and made sweet for me to gaze upon?” And Allah said: “O Adam, this is your maid Eve. Do you love that you would be with her in intimacy?” To which Adam said: “Yes, O Lord, and because you have given me this I must praise you and thank you for as long as I remain.” Allah the Glorified and Exalted then said: “Then call her to me, for she is your woman, and this wife will make pure your lusts.” And Allah had given him lust, and had taught him the wisdom of everything [including lust] before this, and so Adam said: “O Lord, indeed I have called her to you, so what would please you from this?” Allah the Glorified and Exalted then said: “It pleases me that you will teach her the knowledges of my religion.” Adam said: “This is your right upon me, O Lord, if you desire this from me.” Allah the Glorified and Exalted then said: “I do desire this from you, and so I have married her to you, and now you are responsible to me for her.” Hadith from Imam as-Sadiq (AS)
