Surah Muhammad, ayah 31

وَلَنَبۡلُوَنَّكُمۡ حَتَّىٰ نَعۡلَمَ ٱلۡمُجَٰهِدِينَ مِنكُمۡ وَٱلصَّٰبِرِينَ وَنَبۡلُوَاْ أَخۡبَارَكُمۡ ٣١

Walanabluwannakum hattā na'lamal-mujāhidīna minkum was-sābirīna wanabluwa akhbārakum

And We will surely test you until We make evident those who strive among you [for the cause of Allāh] and the patient, and We will test your affairs.
