inna naHnu-l-a'lamoon (inna naHnu al-a'lamoon) (with its many version on this blog) - "indeed, we are the knowers of all," a parody of sorts of what Muslims are wont to put at the end of their statements: "inna-llaahu-l-a'lamoon," "indeed, God is the knower of all."

Phrases and other Arabic (alphabetical according to the first word of the phrase, according to the English alphabet, determined by the beginning letter thereof):
'alaihi, 'alaihaa, 'alahim - "upon him, upon her, upon them" (often as part of a blessing or curse said or written after someone's name); whenever "'alaihi" appears, it can be replaced by any of these terms.

Velaayat-e Faqeh (Persian) - "Government by the Jurisprudent," the theory of theocratic government published, promoted, and implemented by Grand Aayatollaah Ruhollaah Musavi Khomeyni.

Henceforth, a uniform system of transliteration shall be used. It shall be explained here:
The alphabet (name of the letter, how it shall be represented, sound it makes):
alif; a, aa; when short ("a"), like the "a" in "about"; when long ("aa"), like the "a" in "father."
baa; b; as in English
taa; t; a dental "t"
thaa; th; like the "th" in "thing"
jeem; j; as in English
Haa; H; a throaty "h"
khaa; kh; an aspirated "h," like the "ch" in the Scottish word "loch" or the German name "Bach" (no English equivalent)
daal; d; as in English
dhaal; dh; like the "th" in "the"
raa; r
zaa; z; as in English
seen; s; as in English
sheen; sh; as in English
Saad; S; a palatal "s" (no English equivalent)
Daad; D; a palatal "d" (no English equivalent)
Taa; T; a palatal "t" (no English equivalent)
Zaa; Z; a palatal "z" (no English equivalent)
'ayin; '; the epiglottal stop, it is a consonant in its own right, and is different from the hamza' (not always transcribed), which is a glottal stop (no English equivalent)
ghayin; gh; like the French "r" (no English equivalent)
faa; f; as in English
qaaf; q; a "k" further down the throat (no English equivalent)
kaaf; k; as in English
laam; l; as in English
meem; m; as in English
noon; n; as in English
haa; h; as in English
waaw; w, u, oo; when a consonant ("w"), like the "w" in "water"; when a short vowel ("u"), like the "oo" in "book"; when a long vowel ("oo"), like the "oo" in "moon"
yaa; y, i, ee; when a consonant, like "y" in "year"; when a short vowel ("i"), like the "i" in "bit"; when a long vowel ("ee"), like the "ee" in "meet"

Rather than rendering long vowels as double the vowel (aa, ii, uu), We shall render them differently (long "a" = "aa," long "i" = "ee," long "u" = "oo"), which will make it easier to be read.

Five consonants are represented by upper-case letters: Haa, Saad, Daad, Taa, and Zaa.

inna naHnu-l-a'lamoon.
