Al-Ikhlas is not merely the name of this Surah but also the title of its contents, for it deals exclusively with Tauhid. The other Surahs of the Quran generally have been designated after a word occurring in them, but in this Surah the word Ikhlas has occurred nowhere. It has been given this name in view of its meaning and subject matter. Whoever understands it and believes in its teaching, will get rid of shirk (polytheism) completely.

Although these two Surahs of the Qur'an are separate entities and are written in the Mushaf also under separate names, yet they are so deeply related mutually and their contents so closely resemble each other's that they have been designated by a common name Mu'awwidhatayn (the two Surahs in which refuge with Allah has been sought). Imam Baihaqi in Dala'il an-Nubuwwat has written that these Surahs were revealed together, that is why the combined name of both is Mu'awwidhatayn. We are writing the same one Introduction to both, for they discuss and deal with just the same matters and topics. However, they will be explained and commented on separately below.
