He never responded to the charges, but condemned abuses by Russian forces in Chechnya.
Ali ibn al-Husayn ibn Ali ibn Hanzala
Ali ibn al- Husayn ibn Ali ibn Hanzala was the tenth Tayyibi Isma'ili" Dāʿī al- Muṭlaq" in Yemen, from 1284 to his death in 1287.
He was the son of al- Husayn, the" maʾdhūn"( senior deputy) to his predecessor, the ninth" Dāʿī", also named Ali ibn al- Husayn, and grandson of the sixth" Dāʿī", Ali ibn Hanzala.
Ali and his grandfather belonged to the Banu Hamdan and were the only ones to break the monopoly of the Qurayshi Ibn al- Walid family on the office of" Dāʿī al- Muṭlaq" during the 13th century.
He was succeeded by another Ibn al- Walid, Ibrahim ibn al- Husayn.
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.

Along with Abu Walid al Masri, Saeed al- Masri and Saif al- Adel, al- Walid opposed the September 11 attacks two months prior to their execution.
