Ta-Ha · 20:121

121. Then Adam and Eve ate of the tree they were forbidden to eat from, then their private areas became exposed to them after they were hidden, and they began to pluck the leaves of the trees of paradise and cover their private areas with them. Adam opposed the command of his Lord, as he did not comply with His order of refraining from eating of the tree, and so he trespassed the bounds towards that which was not allowed for him.
