بِسْمِ اللهِ وَالصَّلَاةُ وَالسَّلَامُ عَلَى رَسُولِ اللهِ، اللَّهُمَّ إِنِّي أَسْأَلُكَ مِنْ فَضْلِكَ، اللَّهُمَّ اعْصِمْنِي مِنَ الشَّيْطَانِ الرَّجِيمِ.
How it is read
Bismillah, was-salatu was-salamu 'ala Rasulillah. Allahumma innee as-aluka min fadlik. Allahumma'simnee minash-shaytanir-rajeem.
What it means
In the name of Allah, and prayers and peace be upon the Messenger of Allah. O Allah, I ask You of Your bounty. O Allah, protect me from Satan the outcast.
