Just seeing the face of the Messenger of Allah (Sallallahu Alayhi Wasallam) even in your dreams changes the chemistry on your face.  Your face becomes different and should become different in the morning that you wake up to.

If you are able to maintain that light, that touch, that look and the reflection of light then it should change your face until the day you die. You will be resurrected a different person on the day of judgement.

– Sayyid Shaykh Muhammad Al-Yaqoubi hafizu Llah –
