Abd al-Aziz ibn Baz

Abdulaziz ibn Abdullah Al Baz (Arabic: عبد العزيز بن عبد الله آل باز, romanized: ʿAbd al-ʿAzīz ibn ʿAbd Allāh Āl Bāz; 21 November 1912 – 13 May 1999), known as Ibn Baz or Bin Baz, was a Saudi Islamic scholar who served as the second Grand Mufti of Saudi Arabia from 1993 until his death in 1999.

Ibn Baz issued a fatwa authorising a wealth tax to support the mujahideen during the anti-Soviet jihad. His endorsement of In Defence of Muslim Lands, principally written by Abdullah Azzam, was a powerful influence in the successful call for jihad against the Soviet Union. It is said to be the first official call for jihad by a nation state against another nation state in modern times.
