The mausoleum of Sa’d ibn Abi Waqqas in Guangzhou (China) is presented as an important testimony to the history of the introduction of Islam in China, which legitimised its inscription as a cultural heritage site in 2013. However, this institutional recognition is not only due to a recent historiographical re-reading, but also to the presence of Muslim migrants. Indeed, while the local Muslim population visited the site very infrequently at the end of the 1990s, this was not the case for the migrant and foreign Muslim population, who have made a lasting contribution to the local religious life in Guangzhou and played a crucial role in the religious redefinition of the site. By focusing on one group in particular, the Pakistani migrants, associated with the Barelvi brotherhood, I will analyse their impact on the revival of Islam in general and Sufi Islam in particular. Indeed, as soon as they arrived in Guangzhou, they participated in (re)establishing the tomb of Sa’d ibn Abi Waqqas at the centre of their practices, developing Sufi networks, while adapting their practices to the local context.
