I once posed this very question to Archangel Gabriel, who supplicated the Lord of Power concerning Ikhlas and received these words from Allah: Ikhlas is a secret known only unto Me. I entrust it to the hearts of those whom I love most intensely among My servants.

'The Study Quran: A New Translation and Commentary'
By Seyyed Hossein Nasr (Author), Caner Karacay Dagli (Author), Maria Massi Dakake (Author), Joseph E.B. Lumbard (Author), Mohammed Rustom (Author)
“The Study Quran is a treasure trove of insights and information. There is nothing quite like it in English: a single volume comprising an accessible translation, a survey of classical commentaries, essays by prominent scholars, informative appendices, and multiple maps. Indeed a massive, unprecedented undertaking.” (Mohammad Hassan Khalil, Associate Professor of Islamic Studies and Director of the Muslim Studies Program, Michigan State University)
