Sura al-Aʿrāf 7:129

قَالُوٓا۟ أُوذِينَا مِن قَبْلِ أَن تَأْتِيَنَا وَمِنۢ بَعْدِ مَا جِئْتَنَا قَالَ عَسَىٰ رَبُّكُمْ أَن يُهْلِكَ عَدُوَّكُمْ وَيَسْتَخْلِفَكُمْ فِى ٱلْأَرْضِ فَيَنظُرَ كَيْفَ تَعْمَلُونَ

qālū ūdhīnā min qabli an tatīanā wa-min baʿdi mā jitanā qalā ʿasā rabbukum an yuhlika ʿadūwakum wa-yastakhlifakum fī l-arḍi fa-yanẓura kayfa taʿmalūna

They said: "We have had (nothing but) trouble, both before and after thou camest to us." He said: "It may be that your Lord will destroy your enemy and make you inheritors in the earth; that so He may try you by your deeds."

حَتَّىٰٓ أَتَىٰنَا ٱلْيَقِينُ
