Du'a of gratitude to Allah

الْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَ، لَا إِلَهَ إِلَّا اللَّهُ وَحْدَهُ لَا شَرِيكَ لَهُ، وَلَهُ الْمُلْكُ وَلَهُ الْحَمْدُ بِيَدِهِ الْخَيْرُ وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ، لَهُ ٱلۡأَسۡمَآءُ ٱلۡحُسۡنَىٰۚ يُسَبِّحُ لَهُۥ مَا فِي ٱلسَّمَٰوَٰتِ وَٱلۡأَرۡضِۖ وَهُوَ ٱلۡعَزِيزُ ٱلۡحَكِيمُ، اللَّهُمَّ صَلِّ وَسَلِّمْ فِي كُلِّ لَحْظَةٍ أَبَدًا عَدَدَ مَعْلُومَاتِكَ عَلَى سَيِّدِنَا مُحَمَّدٍ وَآلِهِ وَصَحْبِهِ وَعَلَى سَائِرِ الْأَنْبِيَاءِ وَالصَّالِحِينَ إِلَى يَوْمِ الدِّينِ

Alhamdu lillahi rabbil-'alamin, la ilaha illallahu wahdahu la sharika lah, wa lahul-mulku wa lahul-hamdu biyadihil-khayru wa huwa 'ala kulli shay'in qadir, lahul-asma'ul-husna yusabbihu lahu ma fis-samawati wal-ardi wa huwal-'azizul-hakim. allahumma salli wa sallim fi kulli lahzatin abadan 'adada ma'lumatika 'ala sayyidina muhammadin wa alihi wa sahbihi wa 'ala sa'iril-anbiya'i was-salihina ila yawmid-din.

Praise be to Allah, Lord of the worlds. There is no god but Allah alone, He has no partner, and to Him belongs the sovereignty, and to Him belongs all praise. In His hand is all goodness, and He has power over all things. His are the most beautiful names. All that is in the heavens and the earth glorifieth Him, and He is the Mighty, the Wise. O Allah, send peace and blessings at every moment forever, to the number of Your knowledge, upon our master Muhammad, his family, his companions, and upon all the prophets and the righteous until the Day of Judgment.

A general supplication combining the tahlīl (Ṣaḥīḥ al-Bukhārī 3293, Ṣaḥīḥ Muslim 2691, with "in His hand is all goodness" as in Jāmiʿ al-Tirmidhī 3428), Qur'an 59:24 and a composed salawat; not a narration from the Prophet (peace be upon him).
