3وَلَقَد فَتَنَّا الَّذينَ مِن قَبلِهِم ۖ فَلَيَعلَمَنَّ اللَّهُ الَّذينَ صَدَقوا وَلَيَعلَمَنَّ الكاذِبينَOmar & OmarWhereas We did already try those who were before them with hardships. Allâh will surely bring to light those who are true in their faith as He will bring to light also the liars (by putting them into troubles).
