2:35 And We said, "O Adam, dwell you and your spouse in Paradise, and (you both) eat freely from wherever you (both) wish. But do not (you two) approach this tree, lest you (both) be of the wrongdoers."
7:20 Then Satan whispered to both of them to make apparent to both of them that which was concealed to both of them of their shame. And he said, "Did not Your Lord forbid you both this tree, except that you two become Angels or you two become of the immortals."
20:121 Then they both ate of it, so their shame became apparent to them, and they began to fasten over themselves from the leaves of Paradise. And Adam disobeyed his Lord and erred.
2:36 Then Satan made (both of) them slip out of it, and he got (both of) them out from that in which they (both) were. And We said, "Go down (all of you), as enemies to one another; and on the earth, for you is a dwelling place and a provision for a period."
7:22 So he made both of them fall by deception. Then when they both tasted the tree, their shame became apparent to both of them, and they began to fasten over themselves the leaves of the Garden. And their Lord called both of them, "Did I not forbid both of you from this tree and say to both of you that Satan is to both of you an open enemy?" 7:23 Both of them said "Our Lord, we have wronged ourselves, and if You do not forgive us and have mercy on us, we will surely be among the losers."
(Both Adam and his wife were responsible, so both of them asked for forgiveness)(Allah knows best)
14:22 And Satan will say, when the matter has been decided, "Indeed, Allah promised you a promise of truth. And I promised you, but I betrayed you. But I had no any authority over you except that I invited you, and you responded to me. So do not blame me, but blame yourselves. I (can)not be your helper, nor (can) you be my helper. Indeed, I deny your association of me before. Indeed, the wrongdoers, for them is a painful punishment."
