Investigating Al-Ikhlaas (faithfulness/ sincerity) phonetically has uncovered its underlying theme of monotheism, which is reflected in the alternate recurrence of the palatalized and velarized forms of the alveolar lateral /1/. The meaning is deduced to be the result of the consistent syntactic structuring, semantic indication, unification of the verse rhymes, and the quality of the long vowels in the sura. Al-Ikhlass is significant also in that it contains five words, out of its fifteen constituent words, that have not recurred else where in the Qur'an with the same structures and meanings. These words thus constitute 5:15, i.e. one third of the total number of words in the sura. Taking into consideration that Al-Ikhlaas alone is considered to be equivalent to one third of the number becomes of great significance. The glorious Qur'an constitutes two parts: prediction and composition. Prediction is also seen as two parts, about the creator, and about creation (or the human being). Al-Ikhlaas is solely devoted to prediction about the creator ; it states the truth about Allah. Accordingly, it is considered one third of the Qur'an.
