Bismillahir Rahmanir Rahim
Assalamu alaikum warahmatullahi wabarakatuhu
When saying an incantation for the ill person, one should say:
Bismillaahi arqiika min kulli shayin
yu'thiika min sharri kulli nafsin
aw `ayni h~aasidin
In the name of Allah do I make incantation over you
from everything that harms you,
from the harm of every soul
or envious evil eye.
may Allah cure you.
In the name of Allah I make incantation over you.
[recorded in Muslim]
