"A man came from Al-Bahrain to the Prophet [SAW] and greeted him with Salam, but he did not return his greeting. He was wearing a gold ring on his hand, and was wearing a silken Jubbah. He took them off, then he greeted him with Salam, and he returned his greeting. Then he said: 'O Messenger of Allah, I came to you just now, and you turned away from me.' He said: 'You had a coal of fire on your hand.' He said: 'Then I have brought many coals.' He said: 'What you have brought with you is no better for us than the stones of Al-Harrah, but it is a temporary convenience of this world.' He said: 'What should I use for a ring?' He said: 'A ring of iron or silver or brass.'"
أَقْبَلَ رَجُلٌ مِنَ الْبَحْرَيْنِ إِلَى النَّبِيِّ ﷺ فَسَلَّمَ فَلَمْ يَرُدَّ عَلَيْهِ وَكَانَ فِي يَدِهِ خَاتَمٌ مِنْ ذَهَبٍ وَجُبَّةُ حَرِيرٍ فَأَلْقَاهُمَا ثُمَّ سَلَّمَ فَرَدَّ عَلَيْهِ السَّلاَمَ ثُمَّ قَالَ يَا رَسُولَ اللَّهِ أَتَيْتُكَ آنِفًا فَأَعْرَضْتَ عَنِّي فَقَالَ إِنَّهُ كَانَ فِي يَدِكَ جَمْرَةٌ مِنْ نَارٍ قَالَ لَقَدْ جِئْتُ إِذًا بِجَمْرٍ كَثِيرٍ قَالَ إِنَّ مَا جِئْتَ بِهِ لَيْسَ بِأَجْزَأَ عَنَّا مِنْ حِجَارَةِ الْحَرَّةِ وَلَكِنَّهُ مَتَاعُ الْحَيَاةِ الدُّنْيَا قَالَ فَمَاذَا أَتَخَتَّمُ قَالَ حَلْقَةً مِنْ حَدِيدٍ أَوْ وَرِقٍ أَوْ صُفْرٍ
