What the evil eye (‘ayn) is

Ibn al-Qayyim gives the classical definition in Zād al-Ma‘ād (4/149): the evil eye is a look of admiration or of hatred from which subtle, unseen essences pass out of the soul of the caster and reach the person looked at, so that harm occurs. And the caster’s soul does not depend on sight: a blind man can be told about something, and his soul can still affect it, even though he never saw it.

The Arabic word comes from ‘āna ya‘īnu, to strike someone with one’s eye. At its root is the caster’s admiration of a thing; his corrupt inner state then follows that admiration, and he uses his gaze to carry its poison to the one he looks at. Allah commanded His Prophet ﷺ to seek refuge from the envier:

وَمِن شَرِّ حَاسِدٍ إِذَا حَسَدَ

wa min sharri ḥāsidin idhā ḥasad

"And from the evil of an envier when he envies."

The relationship between the two terms: every caster of the eye (‘ā’in) is an envier (ḥāsid), but not every envier casts the eye. Because the envier is the broader category, seeking refuge from the envier automatically covers the caster of the eye too. Ibn al-Qayyim pictures the harm as arrows that fly from the soul of the envier towards the one he envies. Sometimes they hit, sometimes they miss. If they find the target exposed, with no protection, they wound him; if they find him alert and armoured, kept safe by his adhkār and his connection to Allah, the arrows find no way in, and may even rebound on the one who shot them.

Proof from the Quran

وَإِن يَكَادُ ٱلَّذِينَ كَفَرُوا۟ لَيُزْلِقُونَكَ بِأَبْصَٰرِهِمْ لَمَّا سَمِعُوا۟ ٱلذِّكْرَ وَيَقُولُونَ إِنَّهُۥ لَمَجْنُونٌۭ ۝ وَمَا هُوَ إِلَّا ذِكْرٌۭ لِّلْعَٰلَمِينَ

wa in yakādu lladhīna kafarū la-yuzliqūnaka bi-abṣārihim lammā sami'ū dh-dhikra wa yaqūlūna innahu la-majnūn — wa mā huwa illā dhikrun lil-'ālamīn

"And indeed, those who disbelieve would almost make you slip with their eyes when they hear the message, and they say, 'Indeed, he is mad.' But it is not except a reminder to the worlds."

A group of the Quran commentators explained the verse: they wished to strike you, O Muhammad, with their eyes — to knock you down and remove you (Tafsīr al-Baghawī).

Proof from the Sunnah

اسْتَعِيذُوا بِاللَّهِ مِنَ الْعَيْنِ فَإِنَّ الْعَيْنَ حَقٌّ

"Seek refuge with Allah from the eye, for the eye is real."

الْعَيْنُ حَقٌّ وَلَوْ كَانَ شَيْءٌ سَابَقَ الْقَدَرَ سَبَقَتْهُ الْعَيْنُ وَإِذَا اسْتُغْسِلْتُمْ فَاغْسِلُوا

"The eye is real. If anything could have outrun the divine decree, the eye would have outrun it. And when you are asked to wash, then wash."

Proof from lived experience

Beyond the texts, the reality of the eye is something practitioners see constantly. One raqi of long experience relates a small case from among the people who came to him for treatment: a woman visited a family, saw their daughter, looked at her hair and praised it. After she left, that beautiful long hair began to fall out — clump after clump. He adds: cases like this are very many.

None of this makes the eye an excuse to live in fear or suspicion. The same texts that affirm it also teach how to be protected from it, and that nothing reaches anyone except by Allah’s decree.
