Waking up from sleep

لَا إِلَهَ إِلَّا اللهُ وَحْدَهُ لَا شَرِيكَ لَهُ، لَهُ الْمُلْكُ وَلَهُ الْحَمْدَ، وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ. سُبْحَانَ اللهِ، وَالْحَمْدُ للهِ، ولَا إِلَهَ إِلَّا اللهُ، وَاللهُ أَكْبَرُ، وَلَا حَوْلَ وَلَا قُوَّةَ إِلَّا بِاللهِ العَلِيِّ الْعَظيِمِ، ربِّ اغْفِرلِي

Transliteration:Laa 'illaha 'illallahu wahdahu la shareeka lahu, lahul-mulku wa lahul-hamdu, wa Huwa 'alaa kulli shay'in Qadeer Subhaanallahi, walhamdu lillaahi, wa laa 'ilaha 'illallahu, wallaahu 'akbar, wa laa hawla wa laa Quwwata 'illaa billaahil-'Aliyyil-'Adheem, Rabbighfir lee

Meaning:There is none worth of worship but Allah alone, Who has no partner, His is the dominion and to Him belongs all praise, and He is able to do all things. Glory is to Allah. Praise is to Allah. There is none worth of worship but Allah. Allah is the Most Great. There is no might and no power except by Allah's leave, the Exalted, the Mighty. My Lord, forgive me.
