One of the most fundamental areas of literary research is the edition of manuscripts and as long as first-hand works do not have a reliable text, other studies have also no basis. One of the notable texts of Persian literature is Mowlana’s Divan-e- Kabir. Fifty years ago, Froozanfar edited this precious book and after him no one has presented a critical and reliable edition, but his edition is criticized by many literary scholars. Considering the big volume of the divan and Mowlana’s style of composition, fake Ghazals enter the Divan. In this paper, we consider the attribution of six Ghazals of Mowlana. We found 3 of them in Attar's book and the other one was found in Sanayie's and Rudaki's books. The last one is also attributed to Ibn Sina. We studied this poets in manuscripts and we paid attention to the validity of manuscripts which has these poems. In this research, the authenticity of the attribution of these poems has been evaluated.
