Warding off evil eye (Nazr)
It has been narrated to us in Tirmidhi, Nasa’i and Ibn Majah on the authority of Abu Saeed al-Khudari (Allah be pleased with him) that he said, the Prophet (Allah bless him and give him peace) use to seek refuge from the devil-jins and the evil-eye of the human being until the mu’awadhatayn (Sura Al-falaq and al-Naas) were revealed.
When they were revealed, he took them and left the others. (other forms of supplications)
(Tirmidhi)
It has been reported in Bazzar and Ibn Sunni on the authority of Anas (Allah bless him and give him peace) who has reported as marfu, ‘that whoever sees something and he likes it, and says, masha Allah la hawla wa la quwwata illa billa, it will not harm.’
It has been reported in Ibn Sunni on the authority of Sahl ibn Hunayf (Allah be please with him) who said, that the Prophet (Allah bless him and give him peace) when he use to fear of anything being afflicted with his eye, he use to say ‘Allahuma Barik fihi’ and it did not harm anything.
