It was also said that the statement ends with His words, “by permission of their Lord, with every decree.” Then a new statement begins: “Peace it is”—that is, the Night of Decree is wholly peace and goodness; there is no evil in it.
Al-Dahhak said: On that night, Allah decrees and ordains nothing but safety.
Mujahid said: This means that the Night of Decree is safe; Satan is unable to commit evil therein or cause any harm therein. (1) (2)
“Until the emergence of dawn”—that is, until the rising of dawn. Al-Kisa'i recited maṭliʿ with the lam vowelled kasrah, whereas the others recited it with fathah, which is the preferred reading, in the sense of “rising,” as a verbal noun. One says: “Dawn rose, rising and rise.” The kasrah reading denotes the place of rising.
