Mishkat al-Masabih 398
‘Abdallah b. ‘Amr said:
We returned from Mecca to Medina with God’s messenger, and when we came to some water on the way some of the people hurriedly performed ablution at the time of the afternoon prayer; but they were too hasty, and when we reached them their heels were dry, no water having touched them. God’s messenger therefore said, “Woe to the heels because of hell! Complete the ablution.” 

Muslim transmitted it.
وَعَن عبد الله بن عَمْرو قَالَ: رَجَعْنَا مَعَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مِنْ مَكَّةَ إِلَى الْمَدِينَةِ حَتَّى إِذا كُنَّا بِمَاء بِالطَّرِيقِ تعجل قوم عِنْد الْعَصْر فتوضؤوا وهم عِجَال فَانْتَهَيْنَا إِلَيْهِم وَأَعْقَابُهُمْ تَلُوحُ لَمْ يَمَسَّهَا الْمَاءُ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «وَيْلٌ لِلْأَعْقَابِ من النَّار أَسْبغُوا الْوضُوء» . رَوَاهُ مُسلم
