عَنِ ابْنِ أَبِي أَوْسٍ عَنْ جَدِّهِ أَوْسٍ رَضِيَ اللَّهُ عَنْهُ قَالَ: رَأَيْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ تَوَضَّأَ وَاسْتَوْكَفَ ثَلَاثًا أَيْ غَسَلَ كَفَّيْهِ (زَادَ فِي رِوَايَةٍ مِنْ طَرِيقٍ آخَرَ) يَعْنِي غَسَلَ يَدَيْهِ ثَلَاثًا، فَقُلْتُ لِشُعْبَةَ: أَدْخَلَهُمَا فِي الْإِنَاءِ أَوْ غَسَلَهُمَا خَارِجًا؟ قَالَ: لَا أَدْرِي
It is narrated from Sayyiduna Aws (may Allah be pleased with him), he says: I saw the Messenger of Allah (peace and blessings be upon him) perform ablution and pour water three times, that is, he washed his palms three times. In another narration it is stated: that is, he washed his hands three times. I asked Imam Shu’bah: “Did he put his hands inside the vessel or did he wash them outside the vessel?” He said: “That I do not know.”
