Abu al-Abbas as-Sabti
Sidi Bel Abbas or Sidi Ahmed abu al-Abbas al-Khazraji as-Sabti (Ceuta 1129 - Marrakesh 1204) is the patron saint of Marrakesh, in the Islamic tradition.
He is also one of the "Seven Saints" (Sabʿatou Rijal) of the city.
His festival was founded by Abu Ali al-Hassan al-Yusi at the instigation of Moulay Ismael.
Al-Abbas was born in Ceuta, but moved to Marrakesh in 1145-6, during the final weeks of the Almohad siege of the city.
For a number of years he lived in a cave on the hill of Igilliz outside Marrakesh, only coming into town on Fridays for the communal prayer.
The Almohad sultan Yaqub al-Mansur was a disciple of al-Abbas.
He asked him to come and live in the city and provided him a house, a hostel for his disciples as well as a madrasa for study.
Teaching was maintained by the sultan's own funds.
Whenever Yaqub al-Mansur visited al-Abbas he made a point of behaving in a humble manner and acting "as a servant".
To al-Abbas, every act of human mercy ("rahma") evoked a merciful response from the all-merciful God ("ar-Rahim").
Al-Abbas summed up his theory of reciprocity with the maxim: "[Divine] Being is actualised by generosity" (al-wujud yanfa ilu bi'l-jud).
The Andalusian philosopher Ibn Rushd visited al-Abbas several times in Marrakesh.
When al-Abbas died in 1204, he was buried at the graveyard of Sidi Marouk, near Bab Taghzout.
In 1605, the Saadian sultan Abu Faris erected a mausoleum for al-Abbas, hoping that the saint's power would help him recover from his epilepsy.
In 1998, sultan Hassan II improved the sanctuary.
It is also the place of his zawiyya.
Al-Abbas's hagiography, "Akhbar Abi'l-Abbas as-Sabti", written by Abu Ya’qub Yusuf ibn Yahya at-Tadili, was in part composed by al-Abbas himself and contains many autobiographical passages.

Al-Abbas ibn al-Walid
Al-ʿAbbās
ibn al-Walīd ibn ʿAbd al-Malik was an Umayyad prince and general, the son of Caliph al-Walid I. A distinguished military leader in the Byzantine–Arab Wars of the early 8th century, especially in partnership with his uncle Maslama ibn Abd al-Malik, he became involved in the civil wars of the mid-740s and was imprisoned.
He died in prison of an epidemic in 750.
Al-Walid I
Al-Walid ibn Abd al-Malik ibn Marwan (circa 674 – 23 February 715), commonly known as al-Walid I , was the sixth Umayyad caliph, ruling from October 705 until his death.
Al-Walid was the eldest son of his predecessor Caliph Abd al-Malik .
While still a prince, he led annual raids against the Byzantines in 695–698 and built or restored fortifications along the Syrian Desert route to Mecca.
He became the heir apparent after the death of Abd al-Malik's brother and designated successor, Abd al-Aziz ibn Marwan, in 704.
Al-Walid largely continued his father's policies of centralization and expansion, and heavily depended on al-Hajjaj ibn Yusuf, his father's powerful viceroy over the eastern half of the Caliphate.
During his reign, Umayyad armies conquered the Maghreb, Hispania, Sind and Transoxiana, expanding the Caliphate to its largest territorial extent.
War spoils from the conquests allowed al-Walid to finance public works of great magnitude, including the Great Mosque of Damascus, the al-Aqsa Mosque in Jerusalem and the Prophet's Mosque in Medina.
He was the first caliph to institute programs for social welfare, aiding the poor and handicapped in Syria.
Though it is difficult to ascertain al-Walid's direct role in the affairs of his caliphate, his reign was marked by domestic peace and prosperity and likely represented the peak of Umayyad power.
