An-Nahl - ১৬:৯৮

فَإِذَا قَرَأْتَ الْقُرْآنَ فَاسْتَعِذْ بِاللّهِ مِنَ الشَّيْطَانِ الرَّجِيمِ
[16:98]
So when you recite the Quran, seek refuge with Allah from the accursed Shaitan,
When thou dost read the Qur'an, seek Allah's protection from Satan the rejected one.
And when thou recitest the Qur'an, seek refuge in Allah from Satan the outcast.
