Pure souls, such as Mirza Abu'l-Fadl, upon him be the Glory of God, spend their nights and days in demonstrating the truth of the Revelation, by adducing conclusive and brilliant proofs and expanding the verities of the Faith, by lifting the veils, promoting the religion of God and spreading His fragrances. (‘Abdu’l-Baha, The Compilation of Compilations, vol. II, Writers and Writing)
