علاج القلق والفزع فى النوم
What to say if you are afraid to go to sleep or feel lonely and depressed:
'A'oothu bikalimaatil-laahit-taammaati min ghadhabihi wa ‘iqaabihi, wa sharri ‘ibaadihi, wa min hamazaatish-shayaateeni wa ‘an yahdhuroon.
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.
