When entering the Khala', the Messenger of Allah [SAW] would take off his ring.  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ إِذَا دَخَلَ الْخَلاَءَ نَزَعَ خَاتَمَهُ  

"The Messenger of Allah [SAW] put on a ring of gold and put its stone toward his palm. Then the people started to wear rings of gold. Then the Messenger of Allah [SAW] threw away his ring and said: 'I will never wear it again,' and the people threw away their rings."  

اتَّخَذَ رَسُولُ اللَّهِ ﷺ خَاتَمًا مِنْ ذَهَبٍ وَجَعَلَ فَصَّهُ مِنْ قِبَلِ كَفِّهِ فَاتَّخَذَ النَّاسُ خَوَاتِيمَ الذَّهَبِ فَأَلْقَى رَسُولُ اللَّهِ ﷺ خَاتَمَهُ وَقَالَ لاَ أَلْبَسُهُ أَبَدًا وَأَلْقَى النَّاسُ خَوَاتِيمَهُمْ  

The Messenger of Allah [SAW] put on a ring of gold and put its stone (Fass) toward his palm. Then the people started to wear rings, and the Messenger of Allah [SAW] discarded it and said: "I will never wear it again."  

أَنَّ رَسُولَ اللَّهِ ﷺ اتَّخَذَ خَاتَمًا مِنْ ذَهَبٍ وَجَعَلَ فَصَّهُ مِمَّا يَلِي كَفَّهُ فَاتَّخَذَ النَّاسُ خَوَاتِيمَ فَطَرَحَهُ النَّبِيُّ ﷺ وَقَالَ لاَ أَلْبَسُهُ أَبَدًا  

"The Prophet [SAW] used to wear a ring of gold, then he discarded it, and put on a ring of silver on which was engraved (the words): 'Muhammad Rasul Allah.' He said: 'No one else should engrave his ring with an inscription like this ring of mine.' Then he put the stone toward the palm of his hand."  

كَانَ النَّبِيُّ ﷺ تَخَتَّمَ خَاتَمًا مِنْ ذَهَبٍ ثُمَّ طَرَحَهُ وَلَبِسَ خَاتَمًا مِنْ وَرِقٍ وَنَقَشَ فِيهِ مُحَمَّدٌ رَسُولُ اللَّهِ وَقَالَ لاَ يَنْبَغِي لأَحَدٍ أَنْ يَنْقُشَ عَلَى نَقْشِ خَاتَمِي هَذَا ثُمَّ جَعَلَ فَصَّهُ فِي بَطْنِ كَفِّهِ  

The Messenger of Allah [SAW] wore a ring of gold for three days, and when his Companions saw it, gold rings became popular. Then he threw it away and we did not realize what he had done. Then he ordered that a ring of silver be made, and that (the words): "Muhammad Rasul Allah" be engraved on it. It remained on the hand of the Messenger of Allah [SAW] until he died, then on the hand of Abu Bakr until he died, then on the hand of 'Umar until he died. Then (it remained) on the hand of 'Uthman for the first six years of his duties, but when he had to write many letters, he gave it to a man from among Ansar who used to seal letters with it. Then the Ansari went out to a well belonging to 'Uthman and the ring fell. They looked for it but could not find it. He ordered that a similar ring be made and engraved (the words): "Muhammad Rasul Allah" on it.  

أَنَّ رَسُولَ اللَّهِ ﷺ لَبِسَ خَاتَمًا مِنْ ذَهَبٍ ثَلاَثَةَ أَيَّامٍ فَلَمَّا رَآهُ أَصْحَابُهُ فَشَتْ خَوَاتِيمُ الذَّهَبِ فَرَمَى بِهِ فَلاَ نَدْرِي مَا فَعَلَ ثُمَّ أَمَرَ بِخَاتَمٍ مِنْ فِضَّةٍ فَأَمَرَ أَنْ يُنْقَشَ فِيهِ مُحَمَّدٌ رَسُولُ اللَّهِ وَكَانَ فِي يَدِ رَسُولِ اللَّهِ ﷺ حَتَّى مَاتَ وَفِي يَدِ أَبِي بَكْرٍ حَتَّى مَاتَ وَفِي يَدِ عُمَرَ حَتَّى مَاتَ وَفِي يَدِ عُثْمَانَ سِتَّ سِنِينَ مِنْ عَمَلِهِ فَلَمَّا كَثُرَتْ عَلَيْهِ الْكُتُبُ دَفَعَهُ إِلَى رَجُلٍ مِنَ الأَنْصَارِ فَكَانَ يَخْتِمُ بِهِ فَخَرَجَ الأَنْصَارِيُّ إِلَى قَلِيبٍ لِعُثْمَانَ فَسَقَطَ فَالْتُمِسَ فَلَمْ يُوجَدْ فَأَمَرَ بِخَاتَمٍ مِثْلِهِ وَنَقَشَ فِيهِ مُحَمَّدٌ رَسُولُ اللَّهِ  

The Messenger of Allah [SAW] put on a ring of gold, and he used to wear its stone (Fass) next to his palm. Then the people started to wear rings of gold. Then the Messenger of Allah [SAW] discarded it, and the people discarded their rings. Then he acquired a ring of silver with which he used to seal letters, but he did not wear it.  

أَنَّ رَسُولَ اللَّهِ ﷺ اتَّخَذَ خَاتَمًا مِنْ ذَهَبٍ وَكَانَ فَصُّهُ فِي بَاطِنِ كَفِّهِ فَاتَّخَذَ النَّاسُ خَوَاتِيمَ مِنْ ذَهَبٍ فَطَرَحَهُ رَسُولُ اللَّهِ ﷺ فَطَرَحَ النَّاسُ خَوَاتِيمَهُمْ وَاتَّخَذَ خَاتَمًا مِنْ فِضَّةٍ فَكَانَ يَخْتِمُ بِهِ وَلاَ يَلْبَسُهُ
