Surah Al-'Ankabut 29:49

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

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.

Translation: Saheeh International

Tafsir

Nay but it that is the Qur’ān which you have brought is clear signs in the breasts of those who have been given knowledge namely the believers who preserve it in their hearts and none denies Our signs except wrongdoers namely the Jews — they denied them after they were manifested to them.
