The Prophets
قَـٰلَ رَبِّ ٱحْكُم بِٱلْحَقِّ ۗ وَرَبُّنَا ٱلرَّحْمَـٰنُ ٱلْمُسْتَعَانُ عَلَىٰ مَا تَصِفُونَ
[The Prophet] has said, "My Lord, judge [between us] in truth. And our Lord is the Most Merciful, the one whose help is sought against that which you describe."

إِنَّهُۥ يَعْلَمُ ٱلْجَهْرَ مِنَ ٱلْقَوْلِ وَيَعْلَمُ مَا تَكْتُمُونَ
Indeed, He knows what is declared of speech, and He knows what you conceal.
وَإِنْ أَدْرِى لَعَلَّهُۥ فِتْنَةٌ لَّكُمْ وَمَتَـٰعٌ إِلَىٰ حِينٍ
And I know not; perhaps it is a trial for you and enjoyment for a time."
