Your Gray Hairs are a Blessing =)

From ‘Amr bin Shu’aib, from his father, from his grandfather, Allah’s Messenger (SAW) said, 

“Do not pluck gray hairs, for they are the light of the Muslim. He who grows a gray hair in Islam, Allah (SWT) writes down for him a good deed for it, expiates a sin for it, and raises him a degree because of it.” [Abu Dawud)]
