Yahya ibn al-Mukhtar reported: Hasan al-Basri, may Allah have mercy on him, said, “Love others moderately and hate others moderately. Some people were extreme in their love of others and were destroyed by it, and some people were extreme in their hatred of others and were destroyed by it. Do not be extreme in your love and do not be extreme in your hatred. Whoever finds his brother sinning beneath a veil should not expose him. Do not spy on your brother, for you have been prohibited from spying. Do not abandon him and do not alienate him.”

عَنْ يَحْيَى بْنِ الْمُخْتَارِ قَالَ الحسن البصري رحمه الله أَحِبُّوا هَوْنًا وَأَبْغِضُوا هَوْنًا فَقَدْ أَفْرَطَ أَقْوَامٌ فِي حُبِّ أَقْوَامٍ فَهَلَكُوا وَأَفْرَطَ أَقْوَامٌ فِي بُغْضِ أَقْوَامٍ فَهَلَكُوا لَا تُفْرِطْ فِي حُبِّكَ وَلَا تُفْرِطْ فِي بُغْضِكَ مَنْ وَجَدَ دُونَ أَخِيهِ سِتْرًا فَلَا يَكْشِفْهُ وَلَا تَجَسَّسْ أَخَاكَ وَقَدْ نُهِيتَ عَنْ أَنْ تَجَسَّسَهُ وَلَا تَحْفِرْ عَنْهُ وَلَا تَنْفُرْ عَنْهُ
