Question:
What should one do if they commit the evil eye?
Answer:
It is narrated from Suhail bin Hunayf رضي الله عنه that indeed the Messenger of Allah صلى الله عليه وسلم said:
«إذا رأى أحدكم ما يعجبه فى نفسه أو ماله فليبرك عليه فإن العين حق»
“When any of you sees something that pleases him in his person or wealth, he should ask for blessing, for indeed the evil eye is true.”
Reference: Musnad Ahmad 447/3, Sunan Ibn Majah, Hadith number 3509, Al-Mustadrak Al-Hakim 215/4, Hadith number 556
He should say: «بسم الله، ما شاء الله، بارك الله.»
Al-Albani has declared it authentic.
