How to Perform Ablution - Section 3
وَعَن أبي رَافع قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: إِذَا تَوَضَّأَ وُضُوءَ الصَّلَاةِ حَرَّكَ خَاتَمَهُ فِي أُصْبُعه. رَوَاهُمَا الدَّارَقُطْنِيّ. وروى ابْن مَاجَه الْأَخير
Abu Rafi‘ said that when God’s messenger performed ablution he moved his ring on his finger. Daraqutni transmitted the two traditions and Ibn Majah transmitted the second.
