Examining Chapter 112 Of The Qur'an.

As-Salaam alaikum,
The Noble Prophet of Islam, Sallallahu alaihi Wasallam, compared reciting chapter 112 of the Holy Qur'an (Surat Ikhlas) to complete recitation of one-third of the entire Qur'an. Reciting this Surat is a means of blessings for the reciter. Note that Allah Ta'ala sent the Qur'an in 3 parts:--

(1) A third is comprised of Legal Rulings.

(2) A third comprises of Exhortations of Promises and Warnings.

(3) A third comprises of Discussing Allah's Names and Attributes.. and
Surat Ikhlas brings together within it those Names and Attributes.

The Surat mentions 2 Names of Allah which together indicate all the Attributes of Perfection. They are not mentioned in any other ayat/verse: "al-Ahad" and "al-Samad". These 2 names indicate the Oneness of the Sacred Being who possesses all the attributes of perfection.

Allah is Ahad-- His Singularity of Existence cannot be shared by another entity.
Allah is Samad-- His Dignity and Sovereignty reaches the extent where all other things in existence depend on for all their needs... Allahu Tabaraka Wa Ta'ala.
