الحجرٰت — Al-Hujurat Ayat 6
يٰٓاَيُّهَا الَّذِيْنَ اٰمَنُوْٓا اِنْ جَاۤءَكُمْ فَاسِقٌۢ بِنَبَاٍ فَتَبَيَّنُوْٓا اَنْ تُصِيْبُوْا قَوْمًاۢ بِجَهَالَةٍ فَتُصْبِحُوْا عَلٰى مَا فَعَلْتُمْ نٰدِمِيْنَ
Yā ayyuhal-lażīna āmanū in jā'akum fāsiqum binaba'in fa tabayyanū an tuṣībū qaumam bijahālatin fa tuṣbiḥū ‘alā mā fa‘altum nādimīn(a).
"O you who have believed, if there comes to you a disobedient one with information, investigate, lest you harm a people out of ignorance and become, over what you have done, regretful."
