الاسراۤء — Al-Isra' Ayat 45

وَاِذَا قَرَأْتَ الْقُرْاٰنَ جَعَلْنَا بَيْنَكَ وَبَيْنَ الَّذِيْنَ لَا يُؤْمِنُوْنَ بِالْاٰخِرَةِ حِجَابًا مَّسْتُوْرًاۙ

Wa iżā qara'tal-qur'āna ja‘alnā bainaka wa bainal-lażīna lā yu'minūna bil-ākhirati ḥijābam mastūrā(n).

"And when you recite the Qur'an, We put between you and those who do not believe in the Hereafter a concealed partition."
