Bulugh al-Maram #319
كتاب الصلاة
وَلِلنَّسَائِيِّ, وَأَبِي دَاوُدَ مِنْ حَدِيثِ رِفَاعَةَ بْنِ رَافِعٍ: «إِنَّهَا لَنْ تَتِمُّ صَلَاةُ أَحَدِكُمْ حَتَّى يُسْبِغَ اَلْوُضُوءَ كَمَا أَمَرَهُ اَللَّهُ, ثُمَّ يُكَبِّرَ اَللَّهَ, وَيَحْمَدَهُ, وَيُثْنِيَ عَلَيْهِ».
And in the narration of an-Nasa'i and Abu Dawud from the Hadith of Rifa'a bin Rafi':
“The Salat (prayer) of one of you will not be complete until he performs Wudu' (ablution) properly as Allah commanded him, then he says Allahu Akbar and Alhamdu lillah and praises Him.”
