About This Surah
This sura is unusual in having as its title a term not mentioned in the body of the sura. Ikhlas conveys the meaning of sincerity in one’s religion and total dedication to the One true God. Because of the importance of this theme in Islam, the Prophet said that this sura, despite its brevity, was equal to one-third of the Qur’an.
