47:31
وَلَنَبْلُوَنَّكُمْ حَتَّىٰ نَعْلَمَ ٱلْمُجَـٰهِدِينَ مِنكُمْ وَٱلصَّـٰبِرِينَ وَنَبْلُوَا۟ أَخْبَارَكُمْ
walanabluwannakum ḥattā naʿlama l-mujāhidīna minkum wal-ṣābirīna wanabluwā akhbārakum
We shall test you to see which of you strive your hardest and are steadfast; We shall test the sincerity of your assertions.
And surely, We shall try you till We test those who strive hard (for the Cause of Allâh) and As-Sâbirûn (the patient), and We shall test your facts (i.e. the one who is a liar, and the one who is truthful).
