He said, "They are the ones who perform istinja' (cleansing after using the bathroom) with water and they do not sleep throughout the night." This is the last information that reached us from the Book of Purification according to the conditions of the two sheikhs, unless they have omitted it.  

قَالُوا يَا رَسُولَ اللَّهِ مَنْ هَؤُلَاءِ الَّذِينَ {فِيهِ رِجَالٌ يُحِبُّونَ أَنْ يَتَطَهَّرُوا وَاللَّهُ يُحِبُّ الْمُطَّهِّرِينَ} [التوبة 108] قَالَ «كَانُوا يَسْتَنْجُونَ بِالْمَاءِ وَكَانُوا لَا يَنَامُونَ اللَّيْلَ كُلَّهُ» هَذَا آخِرُ مَا انْتَهَى إِلَيْنَا مِنْ «كِتَابِ الطَّهَارَةِ» عَلَى شَرْطِ الشَّيْخَيْنِ مَا لَمْ يُخَرِّجَاهُ
