As-Salaam alaikum,
Reciting chapter 112 of the Holy Qur'an, Surah Ikhlas, is compared to complete recitation of one-third of the entire Qur'an. Reciting it is a means of blessings for the reciter. Note that Allah Ta'ala sent the Qur'an in 3 parts:--

(1) A third of it comprises 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 Surah Ikhlas brings together within it those Names and Attributes.

The Surah mentions 2 Names of Allah which together indicate all the Attributes of Perfection. They are not mentioned in any other verse/ayat of the Qur'an: ''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...
