Sa'id ibn Abd al-Malik

Sa'id ibn Abd al-Malik ibn Marwan (Arabic: سعيد بن عبد الملك بن مروان, romanized: Saʿīd ibn ʿAbd al-Malik ibn Marwān; died 750), also known as Saʿīd al-Khayr ('Sa'id the Good'), was an Umayyad prince and governor.

He played a role in the construction of the Dome of the Rock in Jerusalem in the early part of his father Caliph Abd al-Malik's reign (r. 685–705). He governed Mosul for an undetermined period under his father and was responsible for several building and infrastructural works there. Sa'id was later granted property in Mosul's vicinity by his brother, Caliph al-Walid I (r. 705–715), or his cousin, Caliph Umar ibn Abd al-Aziz (r. 717–720), which he developed into an agricultural tract with a canal. In 724 and 725, he led summer campaigns against the Byzantines in Anatolia. During the rule of his nephew, Caliph al-Walid II, between February 743 to April 744, Sa'id served as the governor of Palestine, but was expelled by rebels in the district after al-Walid II's death. Sa'id was killed in the massacre of the Umayyad family near Ramla after the Abbasid toppling of the dynasty in 750.
