Al 'Ankabut, 49 Ayah
29:49
بَلۡ هُوَ ءَايَٰتُۢ بَيِّنَٰتٞ فِي صُدُورِ ٱلَّذِينَ أُوتُواْ ٱلۡعِلۡمَۚ وَمَا يَجۡحَدُ بِـَٔايَٰتِنَآ إِلَّا ٱلظَّٰلِمُونَ ٤٩
Bal Huwa 'Āyātun Bayyinātun Fī Şudūri Al-Ladhīna 'Ūtū Al-`Ilma ۚ Wa Mā Yajĥadu Bi'āyātinā 'Illā Až-Žālimūna
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.
