الله أكبر،
الله أعز من خلقه جميعاً ،
الله أعز مما أخاف وأحذر ،
أعوذ بالله الذي لا إله إلا هو ،
الممسك السموات السبع 
أن يقعن على الأرض إلا بإذنه ،
من شر عبدك فلان ،
وجنوده وأتباعه وأشياعه ،
من الجن والأنس ،
اللهم كن لي جاراً من شرهم ،
جل ثناؤك وعز جارك ، 
وتبارك اسمك ، 
ولا إله غيرك
(ثلاث مرات)
Allāhu Akbar, 
Allāhu a`azzu min khalqihi jamī`a, 
Allāhu a`azzu mimmā akhāfu wa aḥdhar, 
a`ūdhu billāhi ‘l-ladhī lā ilāha illā hū,
almumsikis-samāwātis-sab`i  
an yaqa`na `ala ‘l-arḍi illā bi idhnih,
min sharri `abdika [name of the person], 
wa junūdihi wa atbā`ihi wa ashyā`ih, 
mina ‘l-jinni wa ‘l-ins, 
Allāhumma kun lī jāran min sharrihim,

Allah is the Most Great, 
Mightier than all His creation. 
He is Mightier than what I fear and dread. 
I seek refuge in Allah, Who there is none worthy of worship but Him. 
He is the One Who holds the seven heavens from falling upon the earth except by His command. 
[I seek refuge in You Allah] from the evil of Your slave [name of the person], 
and his helpers, his followers, and his supporters from among the jinn and mankind.
O Allah, be my support against their evil.
Glorious are Your praises
and mighty is Your patronage.
Blessed is Your Name,
there is no true God but You.
(Recite three times in Arabic.)
