Surah Al-Isra, ayah 45

وَإِذَا قَرَأۡتَ ٱلۡقُرۡءَانَ جَعَلۡنَا بَيۡنَكَ وَبَيۡنَ ٱلَّذِينَ لَا يُؤۡمِنُونَ بِٱلۡأٓخِرَةِ حِجَابٗا مَّسۡتُورٗا ٤٥

Wa idhā qara'tal-qur'āna ja'alnā baynaka wabaynal-ladhīna lā yu'minūna bil-ākhirati hijābam mastūrā

And when you recite the Qur’ān, We put between you and those who do not believe in the Hereafter a concealed partition.⁷⁴⁹
