‘Ubadah ibn al-Samit reported: The Prophet, peace and blessings be upon him, said, “Whoever wakes up in the night and says, ‘There is no God but Allah, alone without any partner. To Him belong the dominion and all praise, and He has power over all things. All praise is due to Allah, glory be to Allah, there is no God but Allah, Allah is the greatest, and there is no movement or might but by Allah,’ then he says, ‘O Allah, forgive me,’ or he supplicates to be answered, then if he performs ablution and prays, his prayer will be accepted.”

عن عبادة بن الصامت عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ مَنْ تَعَارَّ مِنْ اللَّيْلِ فَقَالَ لَا إِلَهَ إِلَّا اللَّهُ وَحْدَهُ لَا شَرِيكَ لَهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ الْحَمْدُ لِلَّهِ وَسُبْحَانَ اللَّهِ وَلَا إِلَهَ إِلَّا اللَّهُ وَاللَّهُ أَكْبَرُ وَلَا حَوْلَ وَلَا قُوَّةَ إِلَّا بِاللَّهِ ثُمَّ قَالَ اللَّهُمَّ اغْفِرْ لِي أَوْ دَعَا اسْتُجِيبَ لَهُ فَإِنْ تَوَضَّأَ وَصَلَّى قُبِلَتْ صَلَاتُهُ
