[Machine] The Messenger of Allah ﷺ used to move his ring when performing ablution. Abu Ahmad said, "I heard Ibn Hammad saying that Al-Bukhari, Ma'mar ibn Muhammad ibn 'Ubaidullah ibn Abi Rafi', was denounced in hadith. The sheikh relied on this issue on the evidence from Ali and others."  

كَانَ رَسُولُ اللهِ ﷺ إِذَا تَوَضَّأَ حَرَّكَ خَاتَمَهُ قَالَ أَبُو أَحْمَدَ سَمِعْتُ ابْنَ حَمَّادٍ يَقُولُ قَالَ الْبُخَارِيُّ مَعْمَرُ بْنُ مُحَمَّدِ بْنِ عُبَيْدِ اللهِ بْنِ أَبِي رَافِعٍ مُنْكَرُ الْحَدِيثِ قَالَ الشَّيْخُ فَالِاعْتِمَادُ فِي هَذَا الْبَابِ عَلَى الْأَثَرِ عَنْ عَلِيٍّ وَغَيْرِهِ  

[Machine] I performed ablution for Ali, and whenever he would perform ablution, he would move his ring.  

وَضَّأْتُ عَلِيًّا فَكَانَ إِذَا تَوَضَّأَ حَرَّكَ خَاتَمَهُ  

[Machine] I saw Ibn Umar, when he performed ablution, he moved his ring.  

رَأَيْتُ ابْنَ عُمَرَ إِذَا تَوَضَّأَ حَرَّكَ خَاتَمَهُ
