The Book of Purification and its Sunnah
It was narrated from 'Abdullah bin 'Amr that:
The Messenger of Allah passed by Sa'd when he was performing ablution, and he said: 'What is this extravagance?' He said: 'Can there be any extravagance in ablution?' He said: 'Yes, even if you are on the bank of a flowing river.'"
حَدَّثَنَا مُحَمَّدُ بْنُ يَحْيَى، حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا ابْنُ لَهِيعَةَ، عَنْ حُيَىِّ بْنِ عَبْدِ اللَّهِ الْمَعَافِرِيِّ، عَنْ أَبِي عَبْدِ الرَّحْمَنِ الْحُبُلِيِّ، عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو، أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ مَرَّ بِسَعْدٍ وَهُوَ يَتَوَضَّأُ فَقَالَ ‏"‏ مَا هَذَا السَّرَفُ ‏"‏ ‏.‏ فَقَالَ أَفِي الْوُضُوءِ إِسْرَافٌ قَالَ ‏"‏ نَعَمْ وَإِنْ كُنْتَ عَلَى نَهَرٍ جَارٍ ‏"‏ ‏.‏
