Curing Fear and Insomnia

Khalid bin Walid radiAllahu anhu reported that once he suffered from insomnia.

The Prophet (salAllahu alayhi wasalam) said to him,

" Shall I teach you words that will make you go to sleep when you say them ? "

Allahumma Rabbas Samawaatis-Sab'i, wa ma adhal-lat,

wa Rabbal-aradina, wa ma aqal-lat, wa Rabbash-Shaiateena,

wa ma adhal-lat kun li jaran min sharri khalqika ajma'een ay-yafruta 'alaya ahad-um-minhum, aw ay-yatgha. Azza jaruk, wa tabarakasmuk

O Allah! Lord of the seven Firmaments and whatever they cover,

Lord of the seven earths and whatever they contain,

Creator of the devils and whoever they mislead,

Be my Protector from the evil of all Your Creatures lest some of them may hasten with insolence against me or transgress the bounds. Honoured is he who is in Your Protection and Blessed is Your Name.
