وَعَنْ بُرَيْدَةَ
أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ لِرَجُلٍ عَلَيْهِ خَاتَمٌ مِنْ شَبَهٍ: «مَا لِي أَجِدُ مِنْكَ رِيحَ الْأَصْنَامِ؟» فَطَرَحَهُ ثُمَّ جَاءَ وَعَلَيْهِ خَاتَمٌ مِنْ حَدِيدٍ فَقَالَ: «مَا لِي أَرَى عَلَيْكَ حِلْيَةَ أَهْلِ النَّارِ؟» فَطَرَحَهُ فَقَالَ: يَا رَسُولَ اللَّهِ مِنْ أَيِّ شَيْءٍ أَتَّخِذُهُ؟ قَالَ: «مِنْ وَرِقٍ وَلَا تُتِمَّهُ مِثْقَالا»
The Prophet (sallallahu alayhi wa sallam) said: to a man who was wearing a signet-ring of yellow copper, “How is it that I notice the odour of idols in you?” So he threw it away and came wearing an iron signet- ring, and when he said, “How is it that I see you wearing the adornment of the inhabitants of hell?”
he threw it away and asked God’s messenger what material he should use. He replied, “Silver, but do not let it weigh as much as a mithqal.” Tirmidhi, Abu Dawud and Nasai transmitted it.
Muhyi as-Sunna said there is a sound tradition on the authority of Sahl ibn Sad about the dower that the Prophet (sallallahu alayhi wa sallam) said to a man, “Seek something, even though it should be an iron signet-ring.”
