Hisnul Muslim 112

When turning over during the night

لَا إِلَهَ إِلَّا اللَّهُ الْوَاحِدُ الْقَهَّارُ، رَبُّ السَّمَاوَاتِ وَالْأَرْضِ وَمَا بَيْنَهُمَا الْعَزِيزُ الْغَفَّارُ

Laa 'ilaaha 'illallaahul-Waahidul-Qahhaaru, Rabbus-samaawaati wal'ardhi wa maa baynahumal-'Azeezul-Ghaffaaru.

There is none worthy of worship but Allah, the One, the Victorious, Lord of the heavens and the earth and all that is between them, the All-Mighty, the All-Forgiving. (This is to be said if you turn over in bed during the night.)
