Sayyidina Ubadah ibn Samit (RA) reported that Allah’s Messenger said, “If any on wakes up during the night and says:
“There is no God but Allah. He is Alone and has no partner. To Him belongs the dominion and to Him all praise belongs. And He is over everything Able. Subhan Allah (gorified is Allah) Alhamdu lillah (all praise belongs to Allah) Allahu Akbar (Allah is the Greatest) and there is no power and might save with Allah. “then (he added), “says: “0 Lord forgive me,” or he said, “then he makes a supplication, he will be answered and if he resolves and makes ablution and offers salah , his salah is approved.”
[Ahmed 22738]
