Qur'an 29:49 · Al-Ankaboot

بَلْ هُوَ ءَايَٰتٌۢ بَيِّنَٰتٌۭ فِى صُدُورِ ٱلَّذِينَ أُوتُوا۟ ٱلْعِلْمَ ۚ وَمَا يَجْحَدُ بِـَٔايَٰتِنَآ إِلَّا ٱلظَّٰلِمُونَ

(49) Rather, it [i.e., the Qur’ān] is distinct verses [preserved] within the breasts of those who have been given knowledge. And none reject Our verses except the wrongdoers.
