وَلَقَدۡ فَتَنَّا ٱلَّذِينَ مِن قَبۡلِهِمۡۖ فَلَيَعۡلَمَنَّ ٱللَّهُ ٱلَّذِينَ صَدَقُواْ وَلَيَعۡلَمَنَّ ٱلۡكَٰذِبِينَ
Wa laqad fatannal lazeena min qablihim fala ya'lamannal laahul lazeena sadaqoo wa la ya'lamannal kaazibeen
English Translation
But We have certainly tried those before them, and Allah will surely make evident those who are truthful, and He will surely make evident the liars
