Azazil was an exemplary lover. (He was the symbol of love and devotion.) The others claiming to be lovers are merely poseurs. But in the wake of his extreme love and yearning for Allah, the fellow became argumentative and arrogant, (i.e. he developed amour propre and arrogance;) and he, who was so eminent, became accursed.
Angels are bright still, though the brightest fell; (Shakespeare, Macbeth).
باز آں ابلیس بحث آغاز کرد،
کہ بُدم من سرخرو کردیم ذرد۔
(Roomi)
Then Satan became argumentative and he said: “You were cognizant of my devotion to you, and you had honoured me in view thereof; and now by this controvertial test you have dishonoured and cursed me!”
Note: By referring to Satan as an ideal lover of Allah, The poet has run counter to the theory of Moulana Roomi that the intellect, as opposed to love, is of the Devil.
زیرکی از ابلیس، عشق از آدم است۔

Reason or argument is from Satan and love from Adam.

Azazeel a lone is lover true, others make empty boast,
Through love's extreme, sans obedience, accursed he became in heavenly host.

God's lovers for a moment forget Him not,
They long for Him till their breath does last.

The only true lover was Azazeel, all others only yearn,
It was his boundless love that made him the accursed.
