Birabbil-Falaq in Qur'an 113 means

Birabbil-Falaq is the Arabic phrase for "Lord of the Daybreak" or "Lord of the Dawn" and is the title of the 113th chapter (surah) of the Qur'an. In this chapter, Muslims seek protection and refuge in Allah from the evil of darkness, the harm that may come from the night, and from the harm of those who practice witchcraft or envy. The chapter speaks of seeking Allah's protection and guidance in every aspect of life, particularly from those who may seek to harm or wrong them. Therefore, "Lord of the daybreak" is the correct answer.
