In the chapter "union", we see how Yusuf meets Zulaikha again and restores her beauty and youth. As discussed in class, we have established that Zulaikha's longing for Yusuf mirrors humankind's longing for god. Physical appearances are but a mirror reflecting god's beauty. Yusuf restoring Zulaikha's beauty is symbolic of restoring a sense of piousness in her, something that makes her worthy of God. Yusuf swears by Abraham to fulfil all of Zulaikha's wishes if it were in his power.
He proceeds to fulfil her first two wishes, which is to restore her youth and beauty, secondly, her sight so she can see his face and 'pluck a rose from the garden of countenance'. Youth and beauty in this context, seem to suggest more than just physical appearance, but also suggests a human's ability to reflect God's eternal splendour. Upon shattering her idol and praying for guidance and forgiveness, it is evident that Zulaikha displays piousness which deems her worthy of her youth, which was described to be 'new-found beauty that reached even greater heights than before'.
Ironically, without hesitance, Yusuf restores Zulaikha's youth and sight, not in his capacity, but with divine powers from God through his prayer. When he is in turn being asked by Zulaikha for permission to 'live with him', he is unable to make a decision which is within his human choice. This implies that their union is not a mere physical union, but something spiritual which could allude to the union of God and humankind.
