Silsilat al-Ahadith al-Sahihah

Sayyiduna Salman al-Farsi (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: «اللَّهُمَّ إِنِّي أُشْهِدُكَ وَأُشْهِدُ مَلَائِكَتَكَ وَحَمَلَةَ عَرْشِكَ، وَأُشْهِدُ مَنْ فِي السَّمَاوَاتِ وَمَنْ فِي الْأَرْضِ، أَنَّكَ أَنْتَ اللَّهُ لَا إِلَهَ إِلَّا أَنْتَ وَحْدَكَ لَا شَرِيكَ لَكَ، وَأَشْهَدُ أَنَّ مُحَمَّدًا عَبْدُكَ وَرَسُولُكَ» “Whoever recites this supplication: O Allah! I make You a witness, I make Your angels and (especially) the bearers of the Throne witnesses, and I make all things in the heavens and the earth witnesses that You are God, You alone are the true God, You are One, You have no partner, and I bear witness that Muhammad (peace and blessings be upon him) is Your servant and Messenger. Whoever recites this supplication once, Allah Almighty will free one third of his being from the Fire; whoever recites it twice, Allah Almighty will free two thirds of his being from the Fire; and whoever recites it three times, Allah Almighty will free his entire being from the Fire.”
