Surahs 113 (al-Falaq) and 114 (an-Nas) are called the Mu’awwidhatayn — ‘the two seekings of refuge’ — and have been recited together for protection in Muslim practice from the earliest period. Sahih hadith preserved by both Bukhari and Muslim describe the Prophet reciting these two surahs every night before sleep, blowing into his cupped hands and wiping them over his body, and instructing his community to do the same. They function liturgically as the closing of the Quran in mushaf order and devotionally as the closing of the day. Their pairing is so habitual that they are rarely cited separately in classical practice.
