﴿ قُلِ ٱللَّهُمَّ فَاطِرَ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ عَٰلِمَ ٱلْغَيْبِ وَٱلشَّهَٰدَةِ أَنتَ تَحْكُمُ بَيْنَ عِبَادِكَ فِى مَا كَانُوا۟ فِيهِ يَخْتَلِفُونَ ﴾

“Say: “O God! Originator of the heavens and the earth! Knower of all that is beyond the reach of a created being’s perception, as well as of all that can be witnessed by a creature’s senses or mind! It is Thou who wilt judge between Thy servants [on Resurrection Day] with regard to all on which they were wont to differ!””
