Few studies have investigated the elements that served in constructing particular images of Muhammad, and the role of these images in the formation of the religious identity of the Muslims of the Maghreb and Andalus. Although there are dozens of inroads into this subject, this paper will explore a tradition unique to the Maghreb and Andalus where Muslims of this region sent letters with pilgrims to be read at Muhammad's graveside wherein they addressed him as a living person who has an omnipotent cosmic role, and where he is sought to intercede in the problems that preoccupied them in their daily lives. This practice that lasted from the 9th to the 16th centuries was performed by all spectrums of society such as kings, notables, laymen and more importantly by scholars who represented orthodoxy in many of its hegemonic aspects. The major questions that this paper will address are: Why did these epistles originate uniquely in Maghreb and Andalus? What role did they play in the religiosity of the people of the region? While answering these questions, this paper will discuss only two of the many elements that are thought to have created a conducive environment, in which these epistles emerged, namely the celebration of the Mawlid (the Prophet’s birthday) and the narratives of the pilgrims embodied in what is historically known as al-Ri?la il? ?aybah. Both of these customs, within a very complicated historical framework, knew a big surge in the period in which the practice of sending epistles to Muhammad flourished. No research has been conducted on these epistles, yet these writings strongly suggest a unique religious identity of the Muslims of this region worthy to be explored and studied.
