Reference : Hisn al-Muslim 113

أَعـوذُ بِكَلِمـاتِ اللّهِ التّـامّـاتِ
مِن غَضَـبِهِ وَعِـقابِهِ وَشَـرِّ عِبـادِهِ
وَمِنْ هَمَـزاتِ الشَّـياطينِ وَأَنْ يَحْضـرون
A`ūdhu bikalimāti ‘llāhit-tāmmāti 
min ghaḍabihi wa `iqābihi wa sharri `ibādih,
wa min hamazātish-shayāṭīni wa an yaḥḍurūn.


I seek refuge in the Perfect Words of Allah
from His anger and His punishment,
from the evil of His slaves,
and from the taunts of devils and from their presence.
