Bulugh al-Maram 81
The Book of Purification
The Nullification of Wudu
وَهَذِهِ اَلزِّيَادَةُ فِي هَذَا اَلْحَدِيثِ عِنْدَ أَبِي دَاوُدَ مِنْ حَدِيثِ عَلِيٍّ دُونَ قَوْلِهِ: { اِسْتَطْلَقَ اَلْوِكَاءُ } وَفِي كِلَا الْإِسْنَادَيْنِ ضَعْف ٌ [1] .
Also reported by Abu Da’ud mentioning the above addition without the words “the string is untied”, but both versions are weak.
