Du'a praising the All-Knowing

الْحَمْدُ للهِ رَبِّ الْعَالَمِينَ، صَاحِبِ الْعَظَمَةِ وَالْكِبْرِيَاءِ، يَعْلَمُ مَا فِي الْبَطْنِ وَالْأَحْشَاءِ، فَرَّقَ بَيْنَ الْعُرُوقِ وَالْأَمْعَاءِ، فَسُبْحَانَكَ يَا رَبَّ الْأَرْضِ وَالسَّمَاءِ

Alhamdu lillahi rabbil-'alamin, sahibil-'azamati wal-kibriya', ya'lamu ma fil-batni wal-ahsha', farraqa baynal-'uruqi wal-am'a', fasubhanaka ya rabbal-ardi was-sama'

All praise is due to Allah, the Lord of the worlds, the Possessor of Greatness and Majesty. He knows what is inside the womb and the entrails, and He separated the veins and the intestines. Glory be to You, O Lord of the earth and the sky.

A general supplication, not a narration from the Prophet (peace be upon him).
