Riyad as-Salihin, 1015

Abu Sa'id Al-Khudri (May Allah be pleased with him) reported:

The Messenger of Allah (ﷺ) used to seek protection against the evil of jinn and the evil eyes till Surat Al-Falaq and Surat An-Nas were revealed. After they were revealed, he took to them for seeking Allah's protection and left everything besides them. <b>[At- Tirmidhi]</b>.

وعن أبي سعيد الخدري رضي الله عنه قال ‏:‏ كان رسول الله صلى الله عليه وسلم يتعوذ من الجان، وعين الإنسان، حتى نزلت المعوذتان، فلما نزلتا، أخذ بهما وترك ما سواهما ‏.‏ (‏‏(‏رواه الترمذي وقال ‏:‏حديث حسن ‏)‏‏)‏‏.‏

<b>Guidance from the Hadiths:</b><br> 1) Ruqyah (faith-healing verses), by the Qur’an in general and by the refuge-seeking Surahs and verses in particular, provides protection for the believer against the evil eye and any harm posed by humans or jinns.<br> 2) It points out the merit of the two refuge-seeking Surahs, i.e. Surat al-Falaq and Surat al-Nās, as they contain total resort to Allah Almighty and abandonment of any attachment to worldly means. No one seeks refuge through them with faith and sincerity except that Allah Almighty will grant him refuge.<br> 3) Finding sufficiency in the Qur’an is the way of the fortunate and guided servants of Allah Almighty.
