The Islamic faith was not isolated from the lives of people of different faiths in their worldly life or even in the design of their final resting place after death. It was inevitable that the difference of religious and ideological doctrines affected the design of tombstones in form and content, as the city of Darband in the Middle Ages boasted the penetration of Persian culture among its inhabitants, which influenced the transfer of the Ismaili Shiite doctrine to the population, from which the Muslim artist in Dagestan was inspired by his artistic creations and decorative designs from the forms of its religious buildings, its holy shrines and Applied Arts, which were represented creatively on tombstones. This study highlights the role of Shiite architectural structures and the types of holy shrines of the Guardians and their accessories from the Applied Arts in Iran and the reason why the Muslim artist was inspired by their forms in the designs and decorations of tombstones, in addition to identifying the contents of inscriptions Shiite religious and recorded writings, which varied from quoting the supplication of Imam Hussein or mentioning the names of the Twelver imams or representing some pictograms indicating the adherents of the Shiite doctrine in drawings of birds and animals.
