يَمۡحُواْ ٱللَّهُ مَا يَشَآءُ وَيُثۡبِتُۖ وَعِندَهُۥٓ أُمُّ ٱلۡكِتَٰبِ ٣٩
Allāh eliminates what He wills or confirms, and with Him is the Mother of the Book.1
Translation: Saheeh International (English)
1 The Preserved Slate (al-Lawḥ al-Maḥfūẓ), in which is inscribed the original of every scripture revealed by Allāh.
Each word's meaning and sound
Allah removes whatever good, evil, fortune or misfortune He wills to remove and He confirms whatever He wills. With Him is the Preserved Tablet, which is the source of all of that, and any erasure or confirmation that appears conforms to what is in it.
