Is this true to attribute the Lāmiyyatul arab to al-shanfarā?

Al-shanfarā (6th century BC) with a group of poets such as Taabbata Sharran (“he who has put evil in his armpit”) are among the best known of the sulūk (“brigand”) poets. Shanfarā was depicted as living a life of solitude and hardship based on the looting and plundering. Shanfarā has two long and famous odes. One of them is Tāeiyeh and the other is Lāmiyyatul arab. Lāmiyyatul arab is one of the most famous poems in the Arabic literature which can be as important as Moallaqāt. Lāmiyyatul arab is natural expression of nomad life and far from features of urban life. Shanfarā in this poem has taken pride in following items: homelessness, poverty, looting at cold nights, refusing the life with Breaking, preferring the wild animals to his tribe, simple life, endurance against starvation, courage, taking revenge. Since the Lāmiyyatul arab has been quoted orally from the pre-Islamic times to the Eighth century AD, and was not written in the literary collections, Ibn-e Dorayd among the ancients and Yosuf Khalif and Korenko among the moderns scholars have doubts in its attribution to Shanfarā. On the other hand there are other scholars such as Borokelman, Jorge Yaqoob, Abdo-l Halim Hafni, Foad Bostani and Emil Badie Yaqoob who believed that Lāmiyyatul arab belongs to Shanfarā. This article tries to find that whether Lāmiyyatul arab’s attribution to Shanfarā is true or not.
