Abu-l-Qasim Ahmad ibn al-Husayn ibn Qasi
Abūʾl- Qāsim Aḥmad ibn al- Ḥusayn ibn Qasī( died 1151) was a Sufi, a rebel leader against the Almoravid dynasty in Al- Garb Al- Andalus and governor of Silves for the Almohads.
The main sources for his life are Ibn al- Abbār, Ibn al- Khaṭīb and ʿ Abd al- Wāḥid al- Marrakūsh ī.
The last is the source for his biography in the biographical dictionary of al- Ṣafadī.
He was of native Iberian stock," rūmī al- aṣl" in the words of Ibn al- Abbār.
He was born at Silves, but the date of his birth is unknown.
His name sustains the possibility that he was a descendant of the Banu Qasi, that had once staged a rebellion against the Emirate of Cordoba.
According to Ibn al- Abbār, he was a minor government official at Silves, while Ibn al- Khaṭīb describes him as a spendthrift.
He eventually sold all his goods, gave the money to the poor and became a" murīd".
He studied under Khalaf Allāh al- Andalusī and Ibn Khalīl in Niebla, although he may also have met Ibn al -ʿ Arīf in Almería.
His main influences were the" Encyclopedia of the Brethren of Purity"( Ibn al- Abbār) and the works of al- Ghazālī( Ibn al- Khaṭīb).
Ibn Qasī wrote a treatise" the Removal of the Sandals", this book revolves around Ibn Qasi's Philosophy, Sufism and History.
Ibn Arabi has written a commentary on some parts of this treatise.
He was also an ally and friend of Afonso Henriques, first king of Portugal, and this association eventually led to his assassination at Silves in 1151.
Ibrahim ibn al-Husayn (Ibn al-Walid)
Ibrahim ibn al- Husayn ibn Ali ibn Muhammad ibn al- Walid was the eleventh Tayyibi Isma'ili" Dāʿī al- Muṭlaq" in Yemen, from 1287 to his death in 1328.
Ibn al-Jawzi
ʿ Abd al- Raḥmān b. ʿ Alī b. Muḥammad Abu'l- Faras̲h ̲ b. al- Jawzī, often referred to as Ibn al- Jawzī( Arabic: ابن الجوزي," Ibn al- Jawzī"; ca. 1116 – 16 June 1201) for short, or reverentially as" Imam Ibn al- Jawzī" by Sunni Muslims, was an Arab Muslim jurisconsult, preacher, orator, heresiographer, traditionist, historian, judge, hagiographer, and philologist who played an instrumental role in propagating the Hanbali school of orthodox Sunni jurisprudence in his native Baghdad during the twelfth- century.
During" a life of great intellectual, religious and political activity," Ibn al- Jawzi came to be widely admired by his fellow Hanbalis for the tireless role he played in ensuring that that particular school – historically, the smallest of the four principal Sunni schools of law – enjoy the same level of" prestige" often bestowed by rulers on the Maliki, Shafi'i, and Hanafi rites.
Belonging to a wealthy family, which descended from Abu Bakr, Ibn al- Jawzi received a" very thorough education" during his adolescent years, and was fortunate to train under some of that era's most renowned Baghdadi scholars, including Ibn al- Zāg̲h̲ūnī( d. 1133), Abū Bakr al- Dīnawarī( d. 1137- 8), and Abū Manṣūr al- Jawālīkī( d. 1144- 5).
Although Ibn al- Jawzi's scholarly career continued to blossom over the next few years, he became most famous during the reign of al- Mustadi( d. 1180), the thirty- third caliph of the Abbasid Caliphate, whose support for Hanbalism allowed Ibn al- Jawzi to effectively become" one of the most influential persons" in Baghdad, due to the caliph's approval of Ibn al- Jawzi's public sermonizing to huge crowds in both pastoral and urban areas throughout Baghdad.
In the vast majority of the public sermons delivered during al- Mustadi's reign, Ibn al- Jawzi often presented a stanch defense of the prophet Muhammad's example, and vigorously criticized all those whom he considered to be schismatics in the faith.
At the same time, Ibn al- Jawzi's reputation as a scholar continued to grow due to the substantial role he played in managing many of the most important universities in the area, as well as on account of the sheer number of works he wrote during this period.
As regards the latter point, it is important to note that part of Ibn al- Jawzi's legacy rests on his reputation for having been" one of the most prolific writers" of all time, with later scholars like Ibn Taymīyyah( d. 1328) studying over a thousand works written by Ibn al- Jawzi during their years of training.
As scholars have noted, Ibn al- Jawzi's prodigious corpus," varying in length" as it does, touches upon virtually" all the great disciplines" of classical Islamic study.
Al-Husayn ibn Ali (Ibn al-Walid)
Al- Husayn ibn Ali ibn Muhammad ibn Ja'far ibn Ibrahim ibn al- Walid al- Anf al- Qurashi was the eighth Tayyibi Isma'ili" Dāʿī al- Muṭlaq" in Yemen, from 1230 to his death in 1268.

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.
