عَنْ قَتَادَةَ قَالَ: سَمِعْتُ أَنَسَ بْنَ مَالِكٍ قَالَ: كَانَ أَصْحَابُ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَنَامُونَ وَلَا يَتَوَضَّأُونَ
It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the noble Companions used to sleep and then would not perform a new ablution.
