Anas ibn Malik reported that the Prophet, may Allah bless him and grant him peace, said, "Make things easy and do not make things difficult. Calm people and do not arouse their aversion."  

قَالَ النَّبِيُّ ﷺ يَسِّرُوا وَلاَ تُعَسِّرُوا وَسَكِّنُوا ولا تُنَفِّرُوا  

'Abdullah ibn 'Amr said, "A guest stayed among the tribe of Israel and there was a dog in the house. They said, 'Dog, do not bark at our guest. The puppies were suckling from it. They mentioned it to one of their Prophets who said, 'This is like a community which will come after you and whose fools will overcome its men of knowledge."  

عَنْ عَبْدِ اللهِ بْنِ عَمْرٍو قَالَ نَزَلَ ضَيْفٌ فِي بَنِي إِسْرَائِيلَ وَفِي الدَّارِ كَلْبَةٌ لَهُمْ فَقَالُوا يَا كَلْبَةُ لاَ تَنْبَحِي عَلَى ضَيْفِنَا فَصِحْنَ الْجِرَاءُ فِي بَطْنِهَا فَذَكَرُوا لِنَبِيٍّ لَهُمْ فَقَالَ إِنَّ مَثَلَ هَذَا كَمَثَلِ أُمَّةٍ تَكُونُ بَعْدَكُمْ يَغْلِبُ سُفَهَاؤُهَا عُلَمَاءَهَا
