Imam Ahmad : 11962

حَدَّثَنَا أَسْوَدُ بْنُ عَامِرٍ حَدَّثَنَا شَرِيكٌ عَنْ حُمَيْدٍ قَالَ رَأَيْتُ عِنْدَ أَنَسِ بْنِ مَالِكٍ قَدَحًا كَانَ لِلنَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِيهِ ضَبَّةُ فِضَّةٍ

Has narrated to us [Aswad bin Amir] said, has narrated to us [Sharik] from [Humaid] he said: "I saw at [Anas bin Malik's] side a glass belonging to the Prophet peace and blessings be upon him, which had a chain made of silver.
