Suarah Ikhlas Introdection

Sura Ikhlas, or Surah Tawhid, is the 112th chapter of the Quran. It is one of the Meccan surahs and is found in the 30th part (Juz) of the Quran. This surah is called Tawhid or Ikhlas because it discusses the oneness of Allah and helps people avoid polytheism (shirk).
The main themes of Sura Ikhlas are monotheism and the oneness of Allah, as well as Allah’s independence from others and how all creation is dependent on Him. Many virtues are attributed to Sura Ikhlas, one of which is that it is considered equivalent to one-third of the Quran, and reciting it three times is equal to completing the entire Quran. It is highly recommended to recite this surah in daily prayers. Additionally, there is a narration where the Prophet Muhammad (peace be upon him) compares Imam Ali (peace be upon him) to Sura Ikhlas, stating that just as reciting Sura Ikhlas three times is like reading the whole Quran, loving Amir al-Mu’minin (Ali) with heart, tongue, and actions represents true Islam.
