Al-Husayn ibn Zakarawayh, also known under his assumed name Sahib al-Shama ("Man with the Mole"), was a Qarmatian leader in the Syrian Desert in the early years of the 10th century.
Husayn succeeded him as leader, likewise claiming to be the Mahdi under the name of "Abu'l-Abbas Ahmad ibn Abdallah", and with the title of "Sahib al-Shama" ("Man with the Mole/Birthmark").
He led the Qarmatians on to ravage Homs, Hama, Ba'albek, Ma'arrat al-Numan and even their old base at Salamiyah, from where their rival Fatimid Mahdi, Abdallah, had recently departed heading west to the Maghreb.
They were captured at the locality of al-Daliyah on the Euphrates Road near al-Rahbah, however, and were executed publicly at Baghdad along with other Qarmatian leaders and sympathizers on 13 February 904.
With these defeats, the Qarmatian movement virtually ceased to exist in the Syrian Desert, although their counterparts in Bahrayn remained an active threat for several decades to come.
