وَحَدَّثَنِي مَالِكٌ، أَنَّهُ بَلَغَهُ أَنَّ عِيسَى ابْنَ مَرْيَمَ، كَانَ يَقُولُ لاَ تُكْثِرُوا الْكَلاَمَ بِغَيْرِ ذِكْرِ اللَّهِ فَتَقْسُوَ قُلُوبُكُمْ فَإِنَّ الْقَلْبَ الْقَاسِيَ بَعِيدٌ مِنَ اللَّهِ وَلَكِنْ لاَ تَعْلَمُونَ وَلاَ تَنْظُرُوا فِي ذُنُوبِ النَّاسِ كَأَنَّكُمْ أَرْبَابٌ وَانْظُرُوا فِي ذُنُوبِكُمْ كَأَنَّكُمْ عَبِيدٌ فَإِنَّمَا النَّاسُ مُبْتَلًى وَمُعَافًى فَارْحَمُوا أَهْلَ الْبَلاَءِ وَاحْمَدُوا اللَّهَ عَلَى الْعَافِيَةِ ‏.‏

Malik related to me that he heard that Isa ibn Maryam used tosay, "Do not speak much without the mention of Allah for you willharden your hearts. A hard heart is far from Allah, but you do notknow. Do not look at the wrong actions of people as if you were lords.Look at your wrong actions as if you were slaves. Some people areafflicted by wrong action and some people are protected from it. Bemerciful to the people of affliction and praise Allah for Hisprotection." Translation Not Available
