ملف ١٩٢٢/٥٢٢، جزء ٧ "البحرين: المطالبة الفارسية بالسيادة عليها؛ مفاوضات المعاهدة الفارسية ١٩٢٩-١٩٣٠" [و‎‎٤‎٤‎٨] (١١٢٦/٩٠٠)

The Sunni Persians occasionally intermarry with Arabs, but
it is unusual, for Shiah Persians to do sc.
5. It should be noted that the large ITajdi element
among the Arabs dislike all classes of Persians, but
particularly the Shiahs whom they esteem worse than
Europeans or Jews. They are particularly annoyed by the
Moharram processions, and if not kept in check would at
these times become violent and break up rozekhanes. It
will be recalled that the riots of 1925 were an instance
of this ill-feeling of Hajdis directed against Persians,, an
ill-feeling which still smoulders and would readily burst
into flames.
6. This summer the ill-feeling between the Sunni Arabs
(other than Bajdis) and the Persian Shiahs was better than
it has been for many years past, and the unusual spectacle
was seen of their paying visits to Matims (rozekhanes)
together with Sunni Persians. The ill treatment of Bahama
at Mohammerah before alluded to has undoubtedly had a bad
effect and any entente has received a severe setback, and
if it continues: unabated till next year it will probably
give rise to interference with Mohammerah processions and
rozekhanes.
7. There is an undercurrent of Arab feeling against all
Persians which is directed against their privileged position
and support by the Agency, a support which the Persians are
somewhat apt to throw in their faces. The fact that nof
foreigners can acquire property in Persia and that many
Persians own extremely valuable property, both in real
estate such as gardens, water rights and buildings, m
Bahrain is x unfavourably commented upon, and there is
a feeling that they should be made to return where they
came from. There is no doubt that the abler Persian
merchants are making considerable headway, and now that
customs restrictions have almost killed the trade of Lingeh
and the smaller Gulf ports they tend to concentrate their
business
