Rasulullah berwudhu sekali sekali
Imam Abu Dawud : 120حَدَّثَنَا حُمَيْدُ بْنُ مَسْعَدَةَ حَدَّثَنَا مُعْتَمِرٌ قَالَ سَمِعْتُ لَيْثًا يَذْكُرُ عَنْ طَلْحَةَ عَنْ أَبِيهِ عَنْ جَدِّهِ قَالَدَخَلْتُ يَعْنِي عَلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَهُوَ يَتَوَضَّأُ وَالْمَاءُ يَسِيلُ مِنْ وَجْهِهِ وَلِحْيَتِهِ عَلَى صَدْرِهِ فَرَأَيْتُهُ يَفْصِلُ بَيْنَ الْمَضْمَضَةِ وَالِاسْتِنْشَاقِ
Narrated by Humaid bin Mas’adah, narrated by Mu’tamir, who said: I heard Laits mention a hadith from Thalhah, from his father, from his grandfather, who said: I visited the Prophet, peace and blessings be upon him, while he was performing ablution, with water flowing from his face and beard onto his chest, and I saw him separate rinsing his mouth from sniffing water.
