What to Do After a Bad Dream
أَعُوذُ بِاللَّهِ مِنَ الشَّيْطَانِ الرَّجِيمِ
A'udhu billahi minash-shaytanir-rajeem
I seek refuge in Allah from the accursed Satan. (Practice: spit lightly to the left side 3 times, recite this refuge 3 times, then turn over to the other side from the side one was sleeping on.)
Sahih Muslim 2262
Opening of Ayat al-Kursi (Before Sleep)
اللَّهُ لَا إِلَٰهَ إِلَّا هُوَ الْحَيُّ الْقَيُّومُ لَا تَأْخُذُهُ سِنَةٌ وَلَا نَوْمٌ
Allahu la ilaha illa huwal hayyul qayyumu la ta'khudhuhu sinatun wa la nawm
Allah - there is no god but He, the Ever-Living, the Sustainer. Neither drowsiness nor sleep overtakes Him. (Excerpt from Ayat al-Kursi)
Surah al-Baqarah, 2:255 (excerpt)
