Abu Nu’as was blamed for lauding the Imam (al- Reza), hence one of his companions said to him,
"I have never seen anyone more independent than you. You have something concerning wine, mountains and singing, but you have said nothing concerning Ali b. Musa al-Reza, who is in your time."
Abu Nu’as replied,
"By Allah, I have left this to honor and magnify him. The like of me can say nothing concerning the like of him!"
Then, after on hour, he composed these lines of poetry.
