Sunan an-Nasai Book 48, Hadith 5189

أَخْبَرَنَا أَحْمَدُ بْنُ سُلَيْمَانَ، قَالَ حَدَّثَنَا عُبَيْدُ اللَّهِ، قَالَ حَدَّثَنَا إِسْرَائِيلُ، عَنْ مَنْصُورٍ، عَنْ سَالِمٍ، عَنْ رَجُلٍ، حَدَّثَهُ عَنِ الْبَرَاءِ بْنِ عَازِبٍ، أَنَّ رَجُلاً، كَانَ جَالِسًا عِنْدَ النَّبِيِّ صلى الله عليه وسلم وَعَلَيْهِ خَاتَمٌ مِنْ ذَهَبٍ وَفِي يَدِ رَسُولِ اللَّهِ صلى الله عليه وسلم مِخْصَرَةٌ أَوْ جَرِيدَةٌ فَضَرَبَ بِهَا النَّبِيُّ صلى الله عليه وسلم إِصْبَعَهُ فَقَالَ الرَّجُلُ مَا لِي يَا رَسُولَ اللَّهِ قَالَ ‏"‏ أَلاَ تَطْرَحُ هَذَا الَّذِي فِي إِصْبَعِكَ ‏"‏ ‏.‏ فَأَخَذَهُ الرَّجُلُ فَرَمَى بِهِ فَرَآهُ النَّبِيُّ صلى الله عليه وسلم بَعْدَ ذَلِكَ فَقَالَ ‏"‏ مَا فَعَلَ الْخَاتَمُ ‏"‏ ‏.‏ قَالَ رَمَيْتُ بِهِ ‏.‏ قَالَ ‏"‏ مَا بِهَذَا أَمَرْتُكَ إِنَّمَا أَمَرْتُكَ أَنْ تَبِيعَهُ فَتَسْتَعِينَ بِثَمَنِهِ ‏"‏ ‏.‏ وَهَذَا حَدِيثٌ مُنْكَرٌ ‏.‏

It was narrated from Al-Bara' bin 'Azib that :A man was sitting with the Prophet [SAW] and he was wearing a gold ring. The Messenger of Allah [SAW] had a stick in his hand and the Prophet [SAW] struck his finger. The man said: "What's wrong with me, O Messenger of Allah?" He said: "Why don't you get rid of this thing that is on your finger?" The man took it and threw it away. The Prophet [SAW] saw him after that and said: "What happened to the ring?" He said: "I threw it away." He said: "I did not tell you to do that, rather I told you to sell it and benefit from its price." This Hadith is Munkar
