Salaam 'alaykom. I reblog a lot of photography, but a lot of times i forget to say Ma Sha Allah. Can I cause evil eye on the person on the photos because of this? I'm sorry if this sounds ridiculous.
My way of practicing Islam is to judge a thing’s importance by the amount of attention that the Quran dedicates to it. Since the evil eye is never mentioned in the Quran, I consider it of negligible importance. There are a number of authentic narrations in al-Bukhari, Muslim, al-Muwatta and others that state that the evil eye is a real thing. To answer your question, if you look at a photo and you admire something in it (a person’s clothing, etc.), then it is recommended that you make a prayer for the benefit of the person. Whether your merely looking at a photo can have a negative influence is not something we can determine with any degree of certainty.
