Narated By Ibn 'Abbas : When the Prophet got up at night to offer the night prayer, he used to say: "Allahumma laka-l-hamdu; Anta nuras-samawati wal ardi wa man fihinna. Wa laka-l-hamdu; Anta qaiyim as-samawati wal ardi wa man fihinna. Wa laka-l-hamdu; Anta-l-,haqqun, wa wa'daka haqqun, wa qauluka haqqun, wa liqauka haqqun, wal-jannatu haqqun, wannaru haqqun, was-sa atu haqqun, wan-nabiyyuna huqqun, Mahammadun haqqun, Allahumma laka aslamtu, wa Alaika tawakkaltu, wa bika amantu, wa ilaika anabtu, wa bika Khasamtu, wa ilaika hakamtu, faghfirli ma qaddamtu wa ma akh-khartu, wa ma asrartu, wa ma a'lantu. Anta al-muqaddimu, wa anta al-mu-'akhkhiru. La ilaha il-la anta (or La ilaha ghairuka)"
