An array of mystical poetry, laden with devotional sentiments and strong ‘Alid inclinations, has been attributed to Shams-i Tabrīzī across the Persian Islamic world. Scholars such as Gabrielle van den Berg have sometimes questioned whether these were really authored by Shams-i Tabrīzī. However later scholars have pointed out that it may instead be a question of whether the name Shams-i Tabriz has been used for more than one person. Van den Berg suggests that this identification is the pen name of Rumi. However she acknowledges that, despite the large number of poems attributed to Shams, that comprise the devotional repertoire of the Ismailis of Badakhshan , an overwhelming majority of these cannot be located in any of the existing works of Rumi. Rather, as Virani observes, some of these are located in the "Rose Garden of Shams" (Gulzār-i Shams), authored by Mulukshah, a descendent of the Ismaili Pir Shams, as well as in other works.
