29:3
وَلَقَدْ فَتَنَّا ٱلَّذِينَ مِن قَبْلِهِمْ ۖ فَلَيَعْلَمَنَّ ٱللَّهُ ٱلَّذِينَ صَدَقُوا۟ وَلَيَعْلَمَنَّ ٱلْكَٰذِبِينَ
Wa laqad fatannal lazeena min qablihim fala ya'lamannal laahul lazeena sadaqoo wa la ya'lamannal kaazibeen
We did test those before them, and Allah will certainly know those who are true from those who are false.
