Explanation of the Hadith: {Woe to the heels from the Fire}

The questioner:
The first message in this episode is one that reached the program from the Matrouh Governorate in the Arab Republic of Egypt, signed by one of the brother listeners. He says: A questioner asks and says: The Prophet (peace and blessings be upon him) said, "Complete " and he asks your eminence, Shaykh Salih, to explain this noble hadith and what exactly are the heels? May Allah reward you with good.

The Shaykh:
In the name of Allah, the Most Gracious, the Most Merciful. Praise be to Allah, Lord of the worlds. May Allah send prayers and peace upon our Prophet Muhammad, his family, and all his Companions. And after that, this hadith is established from the Prophet (peace and blessings be upon him), but his saying "complete the wudu" is not from the words of the Messenger (peace and blessings be upon him).

The presenter:
We can see, I mean.

The Shaykh:
Rather, it is an insertion from the words of the narrator. What is from the words of the Messenger (peace and blessings be upon him) is his saying, "Woe to the heels from the Fire." The reason for that is that the Prophet (peace and blessings be upon him) saw people whose heels were shining, meaning the water did not reach them?
So he said (peace and blessings be upon him), "Woe to the heels from the Fire." The heels is the plural of 'aqib, which is the back of the foot. This is because the one performing wudu generally neglects the back of his foot and the sole of his foot, and thinks that the water of wudu reaches them, whereas it may not reach them except through the attention and follow-up of the one performing wudu. Therefore, the Prophet (peace and blessings be upon him) urged ensuring that water reaches these places, the places of the feet and the heels of the legs. The command to complete the wudu is mentioned in hadiths other than this one, as in his saying (peace and blessings be upon him) so let him complete the wudu as Allah commanded him. Completing the wudu means perfecting and completing it, such that nothing remains of the limbs commanded to be washed except that water has reached them and covered them. If the wudu is not completed and is not valid, he saw (peace and blessings be upon him) a man who had a spot on his foot the size of a dirham that water had not reached, so he said (peace and blessings be upon him), "Go back and perfect your wudu." Yes.
