لَا إِلَهَ إِلَّا اللهُ وَحْدَهُ لَا شَرِيكَ لَهُ ، لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ ، وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ ، سُبْحَانَ اللهِ وَالْحَمْدُ لِلهِ ، وَلَا إِلَهَ إِلَّا اللهُ وَاللهُ أَكْـبَرُ ، وَلَا حَوْلَ وَلَا قُوَّةَ إِلَّا بِاللهِ الْعَلِيِّ الْعَظِيمِ رَبِّ اغْفِرْ لِي

The Prophet said : ‘Whoever awakes at night and then says:\n‘None has the right to be worshipped except Allah, alone without associate, to Him belongs sovereignty and praise and He is over all things wholly capable. How perfect Allah is, and all praise is for Allah, and none has the right to be worshipped except Allah, Allah is the greatest and there is no power nor might except with Allah, The Most High, The Supreme.\nand then supplicates:\n‘O my Lord forgive me.’ …will be forgiven’ \n“or he said: ‘and then asks, he will be answered.If he then performs ablution and prays, his prayer will be accepted’.
