Beware of negnot washing your heels properly, for not doing so can lead to them being burnt in the Hellfire! So, perform your ablution thoroughly

Chapter: The obligation of washing the feet completely

Authentic hadith of Sahih Muslim Sahih Muslim 241a

وَحَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا جَرِيرٌ، ح وَحَدَّثَنَا إِسْحَاقُ، أَخْبَرَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ هِلاَلِ بْنِ يِسَافٍ، عَنْ أَبِي يَحْيَى، عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو، قَالَ رَجَعْنَا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم 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 صلى الله عليه وسلم ‏"‏

وَيْلٌ لِلأَعْقَابِ مِنَ النَّارِ أَسْبِغُوا الْوُضُوءَ ‏"

‘Abdullāh ibn ‘Amr (may Allah be pleased with him) reported:

We returned with the Messenger of Allah (may Allah's peace and blessings be upon him) from Makkah to Madīnah, and when we came to some water on the way, some of the people were in a hurry at the time of the ‘Asr prayer and performed ablution hurriedly; and when we reached them, their heels were dry, and no water had touched them. Thereupon, the Messenger of Allah (may Allah's peace and blessings be upon him) said: "Beware of negnot washing your heels properly, for not doing so can lead to them being burnt in the Hellfire! So, perform your ablution thoroughly."

Reported by Muslim (No. 241a, 241c), Abu Dawud (No. 97), An-Nasa’i (No. 111), Ibn Majah (No. 450), Ahmad (No. 6518, 6617, 6681, 6806) and Ad-Darimi (No. 700).

Explanation

The Prophet (may Allah's peace and blessings be upon him) traveled from Makkah to Madīnah with his Companions, and on their way they found water. Some of the Companions hurried to perform ablution for the ‘Asr prayer, so much so that the backs of their feet appeared to the observer to be dry. So, the Prophet (may Allah's peace and blessings be upon him) said: There will be punishment and destruction in Hellfire for those who fail to wash the backs of their feet during ablution. He ordered them to perform ablution perfectly.

Lessons

It is obligatory to wash the feet during ablution. This is because if wiping were permissible, whoever neglects to wash the heel would not be threatened with Hellfire.
It is obligatory to wash the whole parts that must be washed, and whoever leaves even a small part of what must be washed, intentionally and out of negligence, his prayer is not valid.
The Hadīth demonstrates the significance of teaching and guiding the ignorant.
A knowledgeable person should criticize when he sees the neglect of the obligatory and supererogatory acts of worship in an appropriate manner.
Muhammad Is-hāq ad-Dahlawi said: The proper performance of ablution is of three kinds: obligatory: to wash the part once. Sunnah: to wash it three times. Recommended: to wash it three times in a thorough manner.

Explanation in Arabic

سافَرَ النبيُّ صلى الله عليه وسلم من مكةَ إلى المدينةِ ومعه أصحابه، وفي طريقهم وَجَدوا ماءً، فأسرع بالوضوء لصلاة العصر بعضُ الصحابة حتى إنّ مؤخَّرَ أقدامِهم يظهر للناظِر يَبُوستُها من الماء، فقال النبي صلى الله عليه وسلم: عَذابٌ وهلاكٌ في النار للمقصِّرين في غسل مؤخَّرِ القدمِ حين الوضوء، وأمرهم أن يُبالِغوا في إكمال الوضوء.

وجوب غسل الرجلين في الوضوء؛ لأنه لو جاز المسح لما توعّد بالنار مَن ترك غسل العقب.
وجوب تعميم الأعضاء المغسولة بالغسل، وأن من ترك جزءًا يسيرًا مما يجب تطهيره عمدًا وتساهلًا لا تصح صلاته.
أهمية تعليم الجاهل وإرشاده.
العالم ينكر ما يراه من تضييع الفرائض والسنن بالأسلوب المناسب.
قال محمد إسحاق الدهلوي: الإسباغ على ثلاثة أنواع: فرض وهو استيعاب المحل مرة، وسنة وهو الغسل ثلاثًا، ومستحب وهو الإطالة مع التثليث.

قَوْله : ( عَنْ هِلَال بْن يَسَاف عَنْ أَبِي يَحْيَى ) أَمَّا ( يَسَاف ) فَفِيهِ ثَلَاث لُغَات : فَتْح الْيَاء وَكَسْرِهَا , وَإِسَاف بِكَسْرِ الْهَمْزَة , قَالَ صَاحِب الْمَطَالِع : يَقُولهُ الْمُحَدِّثُونَ بِكَسْرِ الْيَاء , قَالَ : وَقَالَ بَعْضهمْ : هُوَ بِفَتْحِ الْيَاء لِأَنَّهُ لَمْ يَأْتِ فِي كَلَام الْعَرَب كَلِمَة أَوَّلهَا يَاء مَكْسُور إِلَّا يِسَار لِلْيَدِ , قُلْت : وَالْأَشْهَر عِنْد أَهْل اللُّغَة ( إِسَاف ) بِالْهَمْزَةِ , وَقَدْ ذَكَرَهُ اِبْن السِّكِّيت وَابْن قُتَيْبَة وَغَيْرهمَا فِيمَا يُغَيِّرهُ النَّاس وَيَلْحَنُون فِيهِ , فَقَالَ : هُوَ هِلَال اِبْن إِسَاف. وَأَمَّا ( أَبُو يَحْيَى ) فَالْأَكْثَرُونَ عَلَى أَنَّ اِسْمه ( مِصْدَع ) بِكَسْرِ الْمِيم وَإِسْكَان الصَّاد…
