Waliullah, an eminent Sūfī himself, also began the task of reforming Sufism which had declined extensively into a commercial exploitation of superstition.
On political and socio-economic matters, Waliullah upheld the principle of unity and toleration, condemning sectarianism and Sunni/Shīʿa polemics.
