In 1917 Khayru'llah wrote a letter to Professor Edward Browne of Cambridge.."The Baha'i movement in America became slow and dull since the sad dissension reached the West nineteen years ago. I thought then that to call the people to this Great Truth was equivalent to inviting them into a quarrel. But the visit of Abbas Effendi Abdu'l-Baha to this country, his false teachings, his misrepresentation of Baha'ism, his dissimulation, and the knowledge that his end is nigh, aroused me to rise up for helping the work of God, declaring the Truth, and refuting the false attacks of theologians and missionaries. Now I am struggling hard to vivify the Cause of God, after its having received by the visit of Abbas Effendi a death-blow."
