Translation of the song lyrics Nahan - Niyaz

Nahan (original)

خوش باش كه هر كه راز داند
داند كه خوشی خوشی كشاند
تلخش چو بنوشی و بخندی
در ذات تو تلخیی نماند
برخیز كه ساقی اندر آمد
و آن چون هزار دلبر آمد
ای مطرب جان چو دف به دست آمد
این پرده بزن كه یار مست آمد

Nahan (translation)

Be glad that everyone knows the secret
He knows that happiness brings happiness
Drink bitter and laugh
There is no bitterness in your nature
Get up when the butler came in
And it came as a thousand darlings
O singer John Chou Daf was obtained
Unveil that my friend got drunk
