Kohn-Tavor (2008) identified a collapse layer at the end of Stratum X, dated to the Umayyad period (mid-7th to mid-8th centuries CE). Part of a building in Area F “continued in use during the Abbasid period ,” while another part “was destroyed at the end of the Umayyad period,” its remains filled with crushed pottery and sealed by stone collapse. Kohn-Tavor noted that the destruction might be local or related to the Abbasid–Umayyad wars, but also suggested the earthquake of 749 CE as a possible cause, especially in light of a similar destruction layer found at nearby Mishmar David. Probable archaeoseismic evidence for a mid-8th century destruction has also since been reported in the Antila Well Earthquake in the Lod-Ramla region. Taxel (2013:175) notes that “most of the events of the ʿAbbāsid Revolution were played out elsewhere,” and that Palestine came under Abbasid control with little recorded violence. Christian communities and their churches likewise “appear to have suffered” no harm "at the hands of the ʿAbbāsids (Schick 1995: 90; cf. Gil 1992: 87–88)." He therefore concludes that the destruction is more likely to be related to the mid-8th century CE earthquakes. Taxel adds that if the church at the site survived the mid-8th-century disaster, its later destruction and abandonment may relate "to the political unrest that pervaded the country during the second half of the eighth century (Gil 1992: 280–84; Schick 1995: 91–93, with references)." A Latin account by Stephen, a monk of Mar Saba who died around 796 CE, describes Saracen raids in the late 780s and 790s that devastated settlements including Gaza, Ascalon, Beth Guvrin/ Eleutheropolis, and a place called Sariphaea. However, the identification of Sariphaea remains uncertain, and the fate of the Christian community at Ṣarafand al-Amar after the Umayyad period is unclear.
