Dua to Avoid nightmares, Sleeplessness أَعُوذُ بِكَلِمَاتِ اللَّهِ التَّامَّةِ مِنْ غَضَبِهِ وَعِقَابِهِ وَشَرِّ عِبَادِهِ وَمِنْ هَمَزَاتِ الشَّيَاطِينِ وَأَنْ يَحْضُرُونِ I seek refuge in Allah's Perfect Words from His anger, from His punishment, and from the evil of His creatures, and from the whisperings of the Shayatin, and from their presence .. Sunan Abu Dawud, Book 28,3884-hasan
