Hadith on Wisdom: Parable of one who only shares bad news

Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said, “The parable of one who hears wisdom in a gathering, but then only reports evil from its speaker, is the likeness of one who visits a shepherd. He says: O shepherd, shear off the wool of a sheep for me from your flock. The shepherd says: Go and take the best of them by the ear. So he goes and take the shepherd’s dog by the ear.

عَنْ أَبِي هُرَيْرَةَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ مَثَلُ الَّذِي يَجْلِسُ يَسْمَعُ الْحِكْمَةَ ثُمَّ لَا يُحَدِّثُ عَنْ صَاحِبِهِ إِلَّا بِشَرِّ مَا سَمِعَ كَمَثَلِ رَجُلٍ أَتَى رَاعِيًا فَقَالَ يَا رَاعِي أَجْزِرْنِي شَاةً مِنْ غَنَمِكَ قَالَ اذْهَبْ فَخُذْ بِأُذُنِ خَيْرِهَا فَذَهَبَ فَأَخَذَ بِأُذُنِ كَلْبِ الْغَنَمِ
