✦ Narrated 'Ubada bin As-Samit Radi Allahu Anhu 

The Prophet Sal-Allahu Alaihi wasallam said "Whoever gets up at night and says:

لا إله إلا الله وحده لا شريك له ،‏‏‏‏ له الملك ،‏‏‏‏ وله الحمد ،‏‏‏‏ وهو على كل شىء قدير‏‏

الحمد لله ،‏‏‏‏ وسبحان الله ،‏‏‏‏ ولا إله إلا الله ،‏‏‏‏ والله أكبر ،‏‏‏‏ ولا حول ولا قوة إلا بالله‏

La ilaha illal-lah wahdahu la sharika lahu,

lahu-l-mulk wa lahu-l-hamd wa huwa Ala kulli shayin qadir,

Alhamdulillah wa Subhan Allah, wa La ilaha ilAllah wa Allahu Akbar

wa la hawla wa la Quwata illa Billah

(None has the right to be worshipped but Allah. He is the Only One and has no partners . For Him is the Kingdom and all the praises are due for Him. He is Omnipotent. All the praises are for Allah. All the glories are for Allah. And none has the right to be worshipped but Allah, And Allah is Great And there is neither Might nor Power Except with Allah).

And then says: -- Allahumma, Agfir li (O Allah! Forgive me) or Supplicate (Allah), he will be responded to and if he performs ablution (and prays), his prayer will be accepted."
