Whenever the Prophet (ﷺ) offered the night (Tahajjud) prayer, he used to say, "O Allah! All the Praises
are for You; You are the Light of the Heavens and the Earth. And all the Praises are for You; You are
the Keeper of the Heavens and the Earth. All the Praises are for You; You are the Lord of the Heavens
and the Earth and whatever is therein. You are the Truth, and Your Promise is the Truth, and Your
Speech is the Truth, and meeting You is the Truth, and Paradise is the Truth and Hell (Fire) is the
Truth and all the prophets are the Truth and the Hour is the Truth. O Allah! I surrender to You, and
believe in You, and depend upon You, and repent to You, and in Your cause I fight and with Your
orders I rule. So please forgive my past and future sins and those sins which I did in secret or in
public. It is You Whom I worship, None has the right to be worshipped except You ." (See Hadith No.
329,Vol. 8)
Sahih al-Bukhari Book 97, Hadith 124
The Prophet (ﷺ) said "The most superior way of asking for forgiveness from Allah is: 'Allahumma anta
Rabbi la ilaha illa anta, Khalaqtani wa ana `Abduka, wa ana `ala `ahdika wa wa`dika mastata`tu,
A`udhu bika min Sharri ma sana`tu, abu'u Laka bini`matika `alaiya, wa abu'u laka bidhanbi faghfir lee
fa innahu la yaghfiru adhdhunuba illa anta." The Prophet (ﷺ) added. "If somebody recites it during the day
with firm faith in it, and dies on the same day before the evening, he will be from the people of
Paradise; and if somebody recites it at night with firm faith in it, and dies before the morning, he will
be from the people of Paradise."
