Allah's omniscience and justice

قُلْ كَفَىٰ بِٱللَّهِ بَيْنِى وَبَيْنَكُمْ شَهِيدًا ۖ يَعْلَمُ مَا فِى ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ ۗ وَٱلَّذِينَ ءَامَنُوا۟ بِٱلْبَـٰطِلِ وَكَفَرُوا۟ بِٱللَّهِ أُو۟لَـٰٓئِكَ هُمُ ٱلْخَـٰسِرُونَ

Say, "Sufficient is Allāh between me and you as Witness. He knows what is in the heavens and earth. And they who have believed in falsehood and disbelieved in Allāh - it is those who are the losers."

وَلَنَبْلُوَنَّكُمْ حَتَّىٰ نَعْلَمَ ٱلْمُجَـٰهِدِينَ مِنكُمْ وَٱلصَّـٰبِرِينَ وَنَبْلُوَا۟ أَخْبَارَكُمْ

And We will surely test you until We make evident those who strive among you [for the cause of Allāh] and the patient, and We will test your affairs.
