And certainly We tried those who were before them. So God shall surely know those who are sincere in their faith — a knowledge of direct vision — and He shall surely know those who are liars regarding it.
- 29:33
وَلَقَدْ فَتَنَّا الَّذِينَ مِنْ قَبْلِهِمْ ۖ فَلَيَعْلَمَنَّ اللَّهُ الَّذِينَ صَدَقُوا وَلَيَعْلَمَنَّ الْكَاذِبِينَ
We had tried those who were before them so that God knew who spoke the truth, and who were liars.
