Allah's absolute knowledge (Ghayb and Shahādah)

قُلِ ٱللَّهُمَّ فَاطِرَ ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ عَـٰلِمَ ٱلْغَيْبِ وَٱلشَّهَـٰدَةِ أَنتَ تَحْكُمُ بَيْنَ عِبَادِكَ فِى مَا كَانُوا۟ فِيهِ يَخْتَلِفُونَ

Say, "O Allāh, Creator of the heavens and the earth, Knower of the unseen and the witnessed, You will judge between your servants concerning that over which they used to differ."
