A man came to the Prophet ﷺ and he was wearing a signet-ring of yellow copper. He said to him: How is it that I notice the odour of idols in you? So he threw it away, and came wearing an iron signet ring. He (the Prophet) said: What is it that I see you wearing the adornment of the inhabitants of Hell? So he threw it away. He asked: Messenger of Allah, what material I must use? He said: Make it of silver, but do not weigh it as much as a mithqal, The narrator Muhammad did not say: " 'Abd Allah b. Muslim," and al-Hasan did not say: "al-Sulami al-Marwazi."  

أَنَّ رَجُلاً جَاءَ إِلَى النَّبِيِّ ﷺ وَعَلَيْهِ خَاتَمٌ مِنْ شَبَهٍ فَقَالَ لَهُ مَا لِي أَجِدُ مِنْكَ رِيحَ الأَصْنَامِ فَطَرَحَهُ ثُمَّ جَاءَ وَعَلَيْهِ خَاتَمٌ مِنْ حَدِيدٍ فَقَالَ مَا لِي أَرَى عَلَيْكَ حِلْيَةَ أَهْلِ النَّارِ فَطَرَحَهُ فَقَالَ يَا رَسُولَ اللَّهِ مِنْ أَىِّ شَىْءٍ أَتَّخِذُهُ قَالَ اتَّخِذْهُ مِنْ وَرِقٍ وَلاَ تُتِمَّهُ مِثْقَالاً وَلَمْ يَقُلْ مُحَمَّدٌ عَبْدِ اللَّهِ بْنِ مُسْلِمٍ وَلَمْ يَقُلِ الْحَسَنُ السُّلَمِيِّ الْمَرْوَزِيِّ  

The signet-ring of the Prophet ﷺ was of iron polished with silver. Sometimes it remained in my possession. Al-Mu'ayqib was in charge of the signet-ring of the Prophet ﷺ.  

كَانَ خَاتَمُ النَّبِيِّ ﷺ مِنْ حَدِيدٍ مَلْوِيٌّ عَلَيْهِ فِضَّةٌ قَالَ فَرُبَّمَا كَانَ فِي يَدِهِ قَالَ وَكَانَ الْمُعَيْقِيبُ عَلَى خَاتَمِ النَّبِيِّ ﷺ  

The Messenger of Allah ﷺ said to me: Say: O Allah, guide me, and set me right. Remember by guidance (hidayah) the showing of the straight path, and remember by setting right (sadad) the setting right of an arrow. Then pointing to the middle finger and the one next to it, he said: He forbade me to wear a signet-ring on this finger of mine or on this (Asim was doubtful). He forbade me to wear qassiyyah (qasi garments) and mitharah. Abu Burdah said: We asked 'Ali: What is qasiyyah ? He said: These are garments imported to us from Syria or Egypt. They are stripped and marked like citrons. And mitharah was a thing made by women for their husbands.  

لِي رَسُولُ اللَّهِ ﷺ قُلِ اللَّهُمَّ اهْدِنِي وَسَدِّدْنِي وَاذْكُرْ بِالْهِدَايَةِ هِدَايَةَ الطَّرِيقِ وَاذْكُرْ بِالسَّدَادِ تَسْدِيدَكَ السَّهْمَ قَالَ وَنَهَانِي أَنْ أَضَعَ الْخَاتَمَ فِي هَذِهِ أَوْ فِي هَذِهِ لِلسَّبَّابَةِ وَالْوُسْطَى شَكَّ عَاصِمٌ وَنَهَانِي عَنِ الْقَسِّيَّةِ وَالْمِيثَرَةِ قَالَ أَبُو بُرْدَةَ فَقُلْنَا لِعَلِيٍّ مَا الْقَسِّيَّةُ قَالَ ثِيَابٌ تَأْتِينَا مِنَ الشَّامِ أَوْ مِنْ مِصْرَ مُضَلَّعَةٌ فِيهَا أَمْثَالُ الأُتْرُجِّ قَالَ وَالْمِيثَرَةُ شَىْءٌ كَانَتْ تَصْنَعُهُ النِّسَاءُ لِبُعُولَتِهِنَّ
