Supplication when turning over in bed at night

لَآ اِلٰهَ اِلَّا اللّٰهُ الْوَاحِدُ الْقَهَّارُ رَبُّ السَّمٰوٰتِ وَالْاَرْضِ وَمَا بَيْنَهُمَا الْعَزِيْزُ الْغَفَّارُ

There is no deity except Allah, the One, the Prevailing, Lord of the heavens and the earth and (of) whatever is between them, the Almighty, the Most Forgiving.
