Narrated `Asim al-Ahwal:I saw the drinking bowl of the Prophet (ﷺ) with Anas bin Malik, and it had been broken, and he had mended it with silver plates. That drinking bowl was quite wide and made of Nadar wood, Anas said, "I gave water to the Prophet (ﷺ) in that bowl more than so-and-so (for a long period)." Ibn Seereen said: Around that bowl there was an iron ring, and Anas wanted to replace it with a silver or gold ring, but Abu Talha said to him, "Do not change a thing that Allah's Messenger (ﷺ) has made." So Anas left it as it was.
حَدَّثَنَا الْحَسَنُ بْنُ مُدْرِكٍ، قَالَ حَدَّثَنِي يَحْيَى بْنُ حَمَّادٍ، أَخْبَرَنَا أَبُو عَوَانَةَ، عَنْ عَاصِمٍ الأَحْوَلِ، قَالَ رَأَيْتُ قَدَحَ النَّبِيِّ صلى الله عليه وسلم عِنْدَ أَنَسِ بْنِ مَالِكٍ، وَكَانَ قَدِ انْصَدَعَ فَسَلْسَلَهُ بِفِضَّةٍ قَالَ وَهْوَ قَدَحٌ جَيِّدٌ عَرِيضٌ مِنْ نُضَارٍ. قَالَ قَالَ أَنَسٌ لَقَدْ سَقَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم فِي هَذَا الْقَدَحِ أَكْثَرَ مِنْ كَذَا وَكَذَا. قَالَ وَقَالَ ابْنُ سِيرِينَ إِنَّهُ كَانَ فِيهِ حَلْقَةٌ مِنْ حَدِيدٍ فَأَرَادَ أَنَسٌ أَنْ يَجْعَلَ مَكَانَهَا حَلْقَةً مِنْ ذَهَبٍ أَوْ فِضَّةٍ فَقَالَ لَهُ أَبُو طَلْحَةَ لاَ تُغَيِّرَنَّ شَيْئًا صَنَعَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم فَتَرَكَهُ.
