O dear friends of ‘Abdu’l‑Bahá! A message hath been sent verbally with Áqá Mírzá ‘Alí-Akbar-i-Nakhjavání in a particular regard, which since it is involved, this pen hath not the opportunity to set it all down in writing. In question is the matter of confining the teaching work to Muslims. Ye should by all means treat this matter as important, and conduct yourselves accordingly, inasmuch as there is an all-embracing wisdom in such a course. Otherwise, those territories will become intractable—nay, more inimical than Iran. Ye must act with extreme caution: This is necessary and essential.
