Al-A'raf · 7:22

22. So Satan brought them down from their high position through trickery and deception. When they ate from the tree which they had been forbidden to eat from, their private parts became exposed and visible to them. So they started to fix leaves from Paradise onto themselves in order to cover up. Their Lord called to them: 'Did I not forbid you both from eating from this tree, and did I not warn you that Satan is your clear enemy?'
