The Fountain of God’s Unity is an address delivered by Hazrat Mirza Bashir-ud-Din Mahmud Ahmad^(ra) on the occasion of Jalsa Salana Qadian in 1906. This essay expounds on shirk, or associating partners with Allah the Almighty, which has plagued humanity since ancient times. Allah sent prophets to eliminate shirk and affirm His Oneness, yet many have resisted this call. God’s decree is that shirk will ultimately be eradicated and His truth will prevail, exposing shirk as the source of all evil.
