Spiritual teacher i guess.. Ibn taymiyya did refer to him as "my sheikh"True,and ibn Taymiya sheikh was non other than Abdul Qadir Jilani that greatAbdul-wahhab's sheikh was a hanafi sufi. People confused his opposition to grave worshippin and bidcah sufism over true tasawwuf. Its the same case with Sheikh ibn Taymiyyah ra.
Sheikh of Ilm tasawaf,matter of fact they burried next to each other in Iraq
