Amaar compliments Baber without saying "Masha’Allah" ("thanks to Allah"), so Baber thinks he has attracted the evil eye. As a consquence, Baber has lots of bad luck. To get rid of the evil eye, Baber helps Amaar with his class for teens (which goes surprisingly well). Rayyan eats chocolate without paying and feels guilty which is the start of a series of things getting stolen. Sarah feels left out because she doesn’t get the office news any more.
Amaar: Baber, times have changed!
Baber: As Imam it is your duty to make sure they do not!
The evil eye is a known concept in Judaism as well, it’s also called the same, "ayin haRa" in Hebrew. The corresponding phrase to the Arabic "Masha’allah" in Hebrew is "bli ayin haRa" and in (butchered) Yiddish "keinahora". The concept is really old, the evil eye is already mentioned in the Talmud (e.g., Brachot 55b, Brachot 20a, Pirke Avot 2:10, Baba Metzia 107b, ) and it appears in Jewish texts throughout the times, e.g., Rashi comments on Genesis 16:5 that Sarah gives the evil eye to Hagar, or the Mishna Brura forbids to give an aliyah to father and son consecutively because of the evil eye (Kerias Hatorah Issues citing Mishna Brura 141:19).
Like in Islam, the evil eye causes bad things to happen to you and you get the evil eye because of jealousy. So how to avoid the evil eye in Judaism? Don’t talk about valuable item you have, your good luck, your children, and so on, or at least add the phrase mentioned above (Wikipedia: Evil Eye In Judaism). Try not to be jealous yourself (Aish Ask the Rabbi: Evil Eye – Ayin Hara). Or, the most simple and currently fashionable choice, wear a piece of red string on your left wrist (Chaviva Gordon-Bennett: Understanding the Ayin Hara). Additionally, you can put a hamsa in your house (Ariela Pelaia: What Is a Hamsa?). Or – follow Maimonides and countless other rationalists, refuse to believe that the evil eye exists and stop worrying about it (Chabad(!): Do You Believe in the “Evil Eye”?).
