Enough, beautiful boy with your sweet, clever ways;
the fire of loving you has set the whole world ablaze.
Why would you need foul naphtha to hold in your mouth?
Your own ruby lips already keep a fire burning there.
Explanation: Naphtha was a flammable fuel; the poet says the beloved's red lips burn on their own, needing no fuel. 'Ruby lips' is a stock Persian image for the beloved's deep red mouth.

بس ای غلام بدیعالجمال شیرینکار
که سوز عشق تو انداخت در جهان آتش
به نفط گنده چه حاجت که بر دهان گیری
تو را خود از لب لعلست در دهان آتش
