40-9 Ahmad ibn Yahya al-Mokattib narrated that Abul Tayyeb Ahmad ibn Muhammad al-Warraq quoted on the authority of Ali ibn Harun al-Hemayri, on the authority of Ali ibn Muhammad ibn Soleiman al-Nowafali, “When Al-Ma’mun established Ali ibn Musa as his successor to the throne, the poets came to Al-Ma’mun and praised Ar-Ridha’ . Al-Ma’mun gave them rewards since the poems that they uttered were in line with Al-Ma’mun’s viewpoints. All the famous poets came except Abu Nuwas. He did not come and did not praise Ar-Ridha’ . When he visited Al-Ma’mun, Al-Ma’mun said, ‘O Abu Nuwas! You know the position that Ali ibn Musa Ar-Ridha’ has in my sight, and how much I respect him. Then why did you procrastinate in praising him for this position while you are the best poet of the time?’ Then Abu Nuwas said,It was said to me that mine was the best rhyme,Articulate in arts of brilliant speech and chime,That I have pearls of beautiful speechBearing fruits in the hands that can reach;‘So why did you refuse to praise the sonOf Musa, and equal to his merits is none?’I said how could I possibly praise and be fairTo one whose father Gabriel did serve and care?’Al-Ma’mun said, “Very well said.” He granted him as much reward as he had granted the other poets altogether and considered him to be high above them all.
