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. [At- Tirmidhi] .
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 ‏.‏
