29:3
وَلَقَدْ فَتَنَّا ٱلَّذِينَ مِن قَبْلِهِمْ ۖ فَلَيَعْلَمَنَّ ٱللَّهُ ٱلَّذِينَ صَدَقُوا۟ وَلَيَعْلَمَنَّ ٱلْكَـٰذِبِينَ
walaqad fatannā alladhīna min qablihim falayaʿlamanna l-lahu alladhīna ṣadaqū walayaʿlamanna l-kādhibīna
We tested those who went before them: God will certainly mark out which ones are truthful and which are lying.
And We indeed tested those who were before them. And Allâh will certainly make (it) known (the truth of) those who are true, and will certainly make (it) known (the falsehood of) those who are liars, (although Allâh knows all that before putting them to test).
