سورة الحـجـرات

يَا أَيُّهَا الَّذِينَ آمَنُوا إِنْ جَاءَكُمْ فَاسِقٌ بِنَبَإٍ فَتَبَيَّنُوا أَنْ تُصِيبُوا قَوْمًا بِجَهَالَةٍ فَتُصْبِحُوا عَلَىٰ مَا فَعَلْتُمْ نَادِمِينَ ﴿٦﴾

Surah al-Hujurat

6. O you who believe! If a sinner comes to you with any news, investigate, lest you harm some people out of ignorance, and you become regretful for what you have done.
