Dua What to say when in fear of afflicting something or someone with one’s eye

اللَّهُمَّ بَارِكْ فِيهِ ⁽¹⁾.

The Evil Eye: To look at something and be impressed with it, causing harm to befall it. This “looking” may or may not involve jealousy, and can occur unintentionally, indeed be part of a person’s nature! A person can even inflict harm on himself. From the supplications for the protection against the Evil Eye: Allahumma barik AAalayh.
‘O Allah, send blessing upon him.’ Ma shaal-lah, la quwwata illa billah. ‘(this is) that which Allah has willed, there is no power except with Allah.’ ‘If you see something from your brother, yourself or wealth which you find impressing, then invoke blessings for it, for the evil eye is indeed true’.
