Kaalien jinhen na ravaya
Dhoolien rave ko
Kar saaien saiyon pariharri
Rang naveela ho

English Translation
Fareed, those who did not enjoy their spouse when their hair was black- hardly any of them enjoy Him when their hair turns grey. So be in love with the Lord, so that your color may ever be new.
Translation: S. S. Khalsa
