Abu Sa‘īd al-Khudri (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) used to seek refuge (with Allah) against the Jinn and the evil eye, until the Mu‘awwidhatayn (Sūrat al-Falaq and Sūrat An-Nās) were revealed. After they had been revealed, he used them for seeking Allah's protection and left everything else.
This Hadīth explains that the Messenger of Allah (may Allah's peace and blessings be upon him) used to seek refuge in Allah, the Exalted, from the evil of the Jinn and the evil eye by means of supplication and Dhikr. For example, he used to say: I seek refuge in Allah from the Jinn and the evil eye. He continued to do so until the Mu‘awwidhatayn (Sūrat al-Falaq and Sūrat An-Nās) were revealed. Afterwards, he mostly used theses two Sūrahs in seeking protection and left other means, because the two Sūrahs contain everything one needs in seeking refuge in Allah against evil.
