Mu'awiya's grave was a visitation site as late as the 10th century. Al-Mas'udi holds that a mausoleum was built over the grave and was open to visitors on Mondays and Thursdays. Ibn Taghribirdi asserts that Ahmad ibn Tulun, the autonomous 9th-century ruler of Egypt and Syria, erected a structure on the grave in 883/84 and employed members of the public to regularly recite the Qur'an and light candles around the tomb.
