Meaning of “al-Khannās” (الخناس)
The word al-Khannās comes from the Arabic root: خ ن س — khanasa, which means: (1) to withdraw, (2) to shrink back, (3) to retreat after appearing, and or (4) to hide after manifesting.
So الخنّاس (al-Khannās) means: (1) “the one who repeatedly retreats”, (2) “the stealthy withdrawer” and (3) “the one who hides after whispering”
It implies a being that approaches, whispers, then quickly disappears when remembered of Allah.
Who is al-Khannās in Surah an-Nās?
In context of this Surah, this refers specifically to Shayṭān (Satan) — the devil who: (1) whispers evil, (2) plants doubts, (3) suggests sins, (4) plays with thoughts, and then retreats immediately when Allah is remembered (e.g., saying Astaghfirullah, Bismillah, or any dhikr).
Al-Khannās as mentioned in an authentic hadith, in which the Prophet ﷺ said:
“Shayṭān sits on the heart of the son of Adam; when he remembers Allah, Shayṭān withdraws.” — Musnad Aḥmad, Sahīh
This behavior perfectly fits the meaning of Khannās.
Context of Sūrat an-Nās
Sūrat an-Nās was revealed as part of the Mu‘awwidhatayn (the two protective surahs) for seeking Allah’s protection from "internal attacks (thoughts, whispers, doubts)" as opposed to Sūrat al-Falaq, which deals with external harms.
Thus:
In Sūrat Falaq believers are asked to seek Divine help from protection from external evils
While in Sūrat Nās believers are prompted to seek Divine help from protection from internal evils (whispers of Shayṭān)
Why is the devil called “al-Khannās”? (Wisdom)
Because this describes how the devil works: (1) He does not attack openly, (2) He works subtly through whispers (waswasa). and (3) He withdraws when resisted by remembrance of Allah which instantly defeat him.
However, he returns repeatedly, coming, whispering, retreating, then returning again. This captures the psychological nature of Satan’s influence. And this persistency on the part of the Satan more often than not makes believers with weak Eeman (faith) to fall into the Satanic trap and commit sin. Remember, it was the Satan which enticed Prophet Adam and Eve to eat fruit of the forbidden tree and made them defy the exclusive Divine commandment.
Here is a overall game plan of Satan to put concept of Al Khannās into reality:
