Hadith on Wudu: Taking care not to rush through ablution

Abdullah ibn Amr reported: We returned with the Messenger of Allah, peace and blessings be upon him, from Mecca to Medina, until we found water by the road. Some people hurried to perform ablution for afternoon prayer, by the time we reached them their heels were dry and had not been wiped with water. The Prophet said, “Woe to the heels from the Hellfire! Perform ablution thoroughly.”

عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو قَالَ رَجَعْنَا مَعَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مِنْ مَكَّةَ إِلَى الْمَدِينَةِ حَتَّى إِذَا كُنَّا بِمَاءٍ بِالطَّرِيقِ تَعَجَّلَ قَوْمٌ عِنْدَ الْعَصْرِ فَتَوَضَّئُوا وَهُمْ عِجَالٌ فَانْتَهَيْنَا إِلَيْهِمْ وَأَعْقَابُهُمْ تَلُوحُ لَمْ يَمَسَّهَا الْمَاءُ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَيْلٌ لِلْأَعْقَابِ مِنْ النَّارِ أَسْبِغُوا الْوُضُوءَ
