It was narrated from Al-Bara' bin 'Azib that :

A man was sitting with the Prophet ﷺ and he was wearing a gold ring. The Messenger of Allah ﷺ had a stick in his hand and the Prophet ﷺ 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 ﷺ 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.

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 ﷺ وَعَلَيْهِ خَاتَمٌ مِنْ ذَهَبٍ وَفِي يَدِ رَسُولِ اللَّهِ ﷺ مِخْصَرَةٌ أَوْ جَرِيدَةٌ فَضَرَبَ بِهَا النَّبِيُّ ﷺ إِصْبَعَهُ فَقَالَ الرَّجُلُ مَا لِي يَا رَسُولَ اللَّهِ قَالَ " أَلاَ تَطْرَحُ هَذَا الَّذِي فِي إِصْبَعِكَ " . فَأَخَذَهُ الرَّجُلُ فَرَمَى بِهِ فَرَآهُ النَّبِيُّ ﷺ بَعْدَ ذَلِكَ فَقَالَ " مَا فَعَلَ الْخَاتَمُ " . قَالَ رَمَيْتُ بِهِ . قَالَ " مَا بِهَذَا أَمَرْتُكَ إِنَّمَا أَمَرْتُكَ أَنْ تَبِيعَهُ فَتَسْتَعِينَ بِثَمَنِهِ " . وَهَذَا حَدِيثٌ مُنْكَرٌ .
