Read and reflect on verse 4624 from Surah Al-Hujuraat: O you who have attained to faith! Avoid most guesswork [about one another] for, behold, some of [such] guesswork is [in itself] a sin; and do not spy ...
يَا أَيُّهَا الَّذِينَ آمَنُوا اجْتَنِبُوا كَثِيرًا مِنَ الظَّنِّ إِنَّ بَعْضَ الظَّنِّ إِثْمٌ ۖ وَلَا تَجَسَّسُوا وَلَا يَغْتَبْ بَعْضُكُمْ بَعْضًا ۚ أَيُحِبُّ أَحَدُكُمْ أَنْ يَأْكُلَ لَحْمَ أَخِيهِ مَيْتًا فَكَرِهْتُمُوهُ ۚ وَاتَّقُوا اللَّهَ ۚ إِنَّ اللَّهَ تَوَّابٌ رَحِيمٌ
O you who have attained to faith! Avoid most guesswork [about one another] for, behold, some of [such] guesswork is [in itself] a sin; and do not spy upon one another, and neither allow yourselves to speak ill of one another behind your backs. Would any of you like to eat the flesh of his dead brother? Nay, you would loathe it! And be conscious of God. Verily, God is an acceptor of repentance, a dispenser of grace!
