Evil Eye is real

According to Islamic tradition the “evil eye” is real, as Prophet Muhammad (صلى الله عليه و سلم). said: “The evil eye is real.The evil eye is from two sources:

1) the evil eye from mankind    

2) the evil eye from Jinn

The evil eye from mankind is confirmed in many narrations, as Abu Sated (radiallahu anh)  said the Prophet  (صلى الله عليه و سلم) said  to seek refuge from jinn’s and the evil eye from mankind. (At-tirmidhi, 2058)
As for evil eye from jinn’s, it has been narrated by Umm Salamah (radiallahu anhaa) that the Prophet  (صلى الله عليه و سلم) saw in her house a slave girl and in her face was sa faa’ah. upon which the Prophet (صلى الله عليه و سلم)  said: ” Seek Ruqyah for her, for verily she is afflicted with a look (evil eye). ” (Al-Bukhari, 5739)
The scholars have said “As-sa-faa’ah”  is the evil  eye from Jinn’s.

The reason for the evil eye is mostly because of envy (envy is to wish  for the prevention of bounty for another person, even though the envier  doesn’t wish for this bounty). The reality of envy is the result of  hatred and malice, which is the result of anger. ( Fath Al-Haq  Al-Mubeen, 219)            
  The  evil eye is like an arrow or spear that leaves the soul of the envier  and goes to the person that is envied. It afflicts the person envied at  times and sometimes it doesn’t. When it doesn’t afflict him, it is  because of the protective methods he uses (whether supplications,  seeking refuge, etc.) Also, when it doesn’t. afflict him, the evil eye  can return to the envier. ( The Medicine of the Prophet (صلى الله عليه و سلم) ,  138)

What  is an important fact to know is that the evil eye has no effect except  by Allah’s will. A man can give himself the evil eye and he can also  give it to others. It can afflict someone without even being seen by  the envier. For example, a blind man cannot see a person, but he can  still cast the evil eye, or perhaps if the person is not around and  they are described to the envier without being seen by him, it can  afflict that person. It can also be afflicted by one being amazed at  himself without being envious to himself or others. The evil eye can be  done by anyone, even a loved one or a righteous person.

So, it  is incumbent on each and every one of us to take the necessary  precautions and try to prevent being affected by the evil eye, and to  say the supplications and remembrance upon seeing something amazing  and good. (Fath Al-Haq Al-Mubeen, 198) If any thing were  to overtake the divine decree (al-qadar) it would be the evil eye.” (Muslim, 2188)

The Prophet (صلى الله عليه و سلم),  said after destiny( al-qadar ) my Ummah  will die mostly due to  Evil Eye.

Evil Eye  (Nazar) takes Man to the graveyard and Camel to the Pot.

Evil Eye makes one fall down from the mountain.

Islam teaches Muslims to seek protection and refuge in Allah from the evils of envy through the recitation of prayers, verses from the Quran and supplications. The hijaab is also key element for protection against the evil eye. And since women are most likely to be afflicted by it, then it is one of the reasons why Allah made the hijaab is obligatory on them – as a means of protection- that is why it is forbidden for believing women to display any of their beauty in front of non-mahrams (any person that a woman is able to marry), as Allah says in the quran:

“And  tell  the  believing  women  to  reduce  [some]  of  their  vision  and  guard  their  private parts  and  not  expose  their  adornment  except  that  which  [necessarily]  appears  thereof and  to  wrap  [a  portion  of]  their  headcovers  over  their  chests  and  not  expose  their adornment  except  to  their  husbands,  their  fathers,  their  husbands’  fathers,  their  sons, their  husbands’  sons,  their  brothers,  their  brothers’  sons,  their  sisters’  sons,  their women,  that  which  their  right  hands  possess,  or  those  male  attendants  having  no physical  desire,  or  children  who  are  not  yet  aware  of  the  private  aspects  of  women. And  let  them  not  stamp  their  feet  to  make  known  what  they  conceal  of  their adornment.  And  turn  to Allah in  repentance,  all  of  you,  O  believers,  that  you  might succeed.”
