HAFEZ
هر که شد محرم دل در حرم یار بماند، وان که این کار ندانست در انکار بماند
Har ke shod mahram-e del dar haram-e yâr bemând, v-ân ke in kâr nadânest dar enkâr bemând
Whoever became intimate with the heart remained in the beloved's sanctuary; whoever knew not this art remained in denial.
Hafez · Divan, Ghazal 178
