Rasulullah berwudhu sekali sekali
Imam Ibnu Majah : 406حَدَّثَنَا أَبُو كُرَيْبٍ حَدَّثَنَا رِشْدِينُ بْنُ سَعْدٍ أَنْبَأَنَا الضَّحَّاكُ بْنُ شُرَحْبِيلَ عَنْ زَيْدِ بْنِ أَسْلَمَ عَنْ أَبِيهِ عَنْ عُمَرَ قَالَرَأَيْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي غَزْوَةِ تَبُوكَ تَوَضَّأَ وَاحِدَةً وَاحِدَةً
