Quote # 2

O my Lord, by virtue of the host of Prophets, Whom You sent with Your abundant grace

Grant me wisdom, as You have granted me a yearning heart; Grant me wine, as You have granted me
the goblet

O my Lord God, for the sake of Mustafa [the Chosen One] Whom You supported at every step

Hold my hand with Your grace and compassion,And be my friend and helper in all my affairs.

I put all my trust in Your power, Even though I am like dust, or humbler still.
