to court poets. The more settled, comfortable and luxurious life in Umayyad courts led to a greater emphasis on the ghazal or love poem. Chief amongst this new breed of poet was Abu Nuwas. Not only did Abu Nuwas spoof the traditional poetic form of the qasida and write many poems in praise of wine, his main occupation was the writing of ever more ribald ghazal many of them openly homosexual. While Nuwas produced risqué but beautiful poems, many of which pushed to the limit what was acceptable under Islam, others produced more religiously themed poetry. It is said that Nuwas struck a bargain with his contemporary Abu al-Alahijah: Abu Nuwas would concentrate on wine and love poems whilst al-Alahijah would write homilies. These homilies expressed views on religion, sin and the afterlife, but occasionally strayed into unorthodox territory. While the work of al-Alahijah was acceptable, others such as the poet Salih ibn 'Abd al-Quddus were executed for heresy. Waddah al-Yaman, now the national poet of Yemen, was also executed for his verse, but this was probably due to his over-familiarity with the wife of the caliph Al-Walid I. Court poets were joined with court singers who simply performed works included Ibrahim al-Mawsili, his son Ishaq al-Mawsili and Ibrahim ibn al-Mahdi son of caliph al-Mahdi. Many stories about these early singers were retold in the Kitab al-Aghani or Book of Songs by Abu al-Faraj al-Isfahani. The Sufi tradition also produced poetry closely linked to religion. Sufism is a mystical interpretation of Islam and it emphasised the allegorical nature of language and writing. Many of the works of Sufi poets appear to be simple ghazal or khamriyyah. Under the guise of the love or wine poem they would contemplate the mortal flesh and attempt to achieve transcendence. Rabia al-Adawiyya, Abd Yazid al-Bistami and Mansur al-Hallaj are some of the most significant Sufi poets, but the poetry and doctrine of al-Hallaj was eventually considered heretic for saying "I am the Truth," which came to be compared as literal incarnation. Al Hallaj was crucified and later became known as a Martyr. The caliph himself could take on the role of court poet with al-Walid II a notable example, but he was widely disliked for his immorality and was deposed after only a year.
