Qur'ān 29:49 · Al-Ankabut (العنكبوت)

بَلْ هُوَ ءَايَـٰتٌۢ بَيِّنَـٰتٌۭ فِى صُدُورِ ٱلَّذِينَ أُوتُوا۟ ٱلْعِلْمَ ۚ وَمَا يَجْحَدُ بِـَٔايَـٰتِنَآ إِلَّا ٱلظَّـٰلِمُونَ

Rather, the Qur'an is distinct verses [preserved] within the breasts of those who have been given knowledge. And none reject Our verses except the wrongdoers.
