It was narrated that Ibn 'Abbas said:
"When the Prophet (ﷺ) got up at night to pray Tahajjud, he said: Allahumma, lakal-hamdu anta nurus-samawati wal-ardi wa man fihinna wa lakal-hamdu anta qayyamus-samawati wal ardi wa man fihinna wa lakal-hamdu, anta haqqun wa wa'duka haqqun wal jannatu haqqun wan-nuru haqqun wan-nabiyyuna haqqun wa Muhammadan haqqun, laka aslant wa 'alaika tawakkaltu wa bika amant. ( O Allah, to You be praise, You are the Light of the heavens and earth and whoever is in them. To You be praise, You are the Sustainer of the Heavens and the earth and whoever is in them. To You be praise, You are the Sovereign of the heavens and earth and whoever is in them. To You be praise; You are True, Your promise is true, Paradise is true, Hell is true, the Hour is true, the Prophets are true and Muhammad is true. To You have I submitted, in You I put my trust and in You I have believed.'" Then (one of the narrators) Qutaibah mentioned some words the meaning of which was: "Wa bika khasamtu wa ilaika hakamtu, ighfirli ma quadrate wa ma akhkhartu wa ma a'lantu antal-muqaddimu wa antal-mu'khkhir, la ilaha illa anta wa la hawla wa la quwwata illa billah (And with Your help I argue [with my opponents, the non-believers], and I take You as a judge [to judge between us]. Forgive me my past and future sins and those that I commit openly. You are the One who puts [some people] back and bring [others] forward. There is no God but You and there is no power and no strength except with Allah).'"
