عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ: ((مَثَلُ الَّذِي يَجْلِسُ فَيَسْمَعُ الْحِكْمَةَ، ثُمَّ لَا يُحَدِّثُ عَنْ صَاحِبِهِ إِلَّا بِشَرٍّ مَا سَمِعَ، كَمَثَلِ رَجُلٍ أَتَى رَاعِيًا فَقَالَ: يَا رَاعِي! اجْزُرْ لِي شَاةً مِنْ غَنَمِكَ، قَالَ: اذْهَبْ فَخُذْ بِأُذُنِ خَيْرِهَا، فَذَهَبَ فَأَخَذَ بِأُذُنِ كَلْبِ الْغَنَمِ))
Sayyiduna Abu Huraira (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Whoever hears a word of wisdom and does not attribute it to the one who said it, but only narrates what he has heard of evil, his example is like that of a man who came to a shepherd and said: O shepherd! Give me a goat that is fit for sacrifice. The shepherd said: Go and grab the ear of the best goat (and take it). But he went and grabbed the ear of the shepherd's dog and took it away."
