Answer
It is narrated on the authority of Burayda (Radhiallaahu Anhu) that once
Khalid ibn Waleed complained to Nabi (Sallallaahu Alayhi Wasallam) of
Insomnia. Nabi (Sallallaahu Alayhi Wasallam) taught him the following Du’aa
to be read when one retires to bed:
Translit: Allaahumma rabbis samaaawaatis sab’a wamaa adhallat wa rabbal
ardheena wamaa aqallat wa rabbas shayaateen wa maa adhallat kun liy jaaran
min sharri khalqika kullihim jamee’an an yafruta alayya ahadun minhum aw an
yanbaghiy azza jaaruka wa jalla thanaa-u-ka wa laa ilaaha ghayruka laa
ilaaha illaa anta.
and Allah Ta’ala Knows Best
