Dua against sleeplessness

Dua against sleeplessness–e.g., for road warriors
In another sound hadith, the Prophet (s) said, “Whoever wakes up from sleep and cannot go back to sleep, and says, “La ilaha illa-Allahu wahdahu la sharika lahu, lahul-mulk wa lahul-hamd, wa huwa ‘ala kulli sha’ in qadeer, al-hamdu lillahi, wa subhan’Allah, wa la ilaha illallahu, wallahu akbar, wala hawla wala quwwata illa billah (there is no god but Allah, He is One and has no partner, to Him belongs all praise and all authority, and He has power over all things, praise be to Allah, glory be to Aliah, there is no god but Allah, Allah is the greatest, there is no power nor any authority but with Allah),’ and then says, ‘Allahumma ighfir li (O Allah, forgive me), or asks some other thing, will be answered, and if he makes wudu and offers a prayer it will be accepted from him.”
