[2] Yazid III was the grandson of great Umayyad caliph Abd al-Malik and his grand mother was Wallada bint al-Abbas ibn al-Jaz al-Absiyya.
[11] On accession, Yazid explained that he had rebelled on behalf of the Book of Allah and the Sunna of His Prophet, and that this entailed ensuring that the strong not prey upon the weak.
He promised abdication if he failed to meet these goals, and held in principle to al-amr shura – to an elected caliphate.
[13] Tabari records Yazid's nickname "the Diminisher" (Naqis), given because he reduced military annuities by 10%,[14] whereas his predecessor had promised a raise.
It supports the Umayyad dynasty up to but not including "the enemy of Allah" al-Walid II, at which point it lays out Yazid's version of the event at al-Bakhra'.
Facing opposition from Juday al-Kirmani, Nasr invited al-Harith ibn Surayj to return from his thirteen-year stay in Turgesh territory.
