وَلَقَدْ فَتَنَّا ٱلَّذِينَ مِن قَبْلِهِمْ ۖ فَلَيَعْلَمَنَّ ٱللَّهُ ٱلَّذِينَ صَدَقُوا۟ وَلَيَعْلَمَنَّ ٱلْكَـٰذِبِينَ
Wa laqad fatannal lazeena min qablihim fala ya'lamannal laahul lazeena sadaqoo wa la ya'lamannal kaazibeen
We tested those who came before them, and God will surely know those who are truthful, and he will surely know the liars.
