Anwār-i Ṣalāḥ-i Dīn bar angēkhta bād
Dar dīda u jān-i ʿāshiqān rēkhta bād
Har jān ki laṭīf gasht u az luṭf guzasht
Bā khāk-i Ṣalāḥ-i Dīn dar āmēkhta bād
May the splendors of Salahuddin be roused,
And poured into the eyes and souls of the lovers.
May every soul that has become refined and has surpassed refinement
Be mingled with the dust of Salahuddin!
