What is the detailed explanation of the hadith "ويل للأعقاب من النار"?

The Hadith (definition) concerning (Woe to the heels from the Fire) revolves around the importance of performing ablution thoroughly and washing the feet completely.

Text of the Hadith: On the authority of Abdullah ibn Amr (may Allah be pleased with them both), the Prophet (peace be upon him) said: "Woe to the heels from the Fire. Perform ablution thoroughly."

Meanings: Woe (ويل): A threat, punishment, and warning. Heels (الأعقاب): The back part of the foot. Prayer has almost overtaken us (أرهقتنا الصلاة): Its time was almost expiring.

Derived Benefits:

1. Obligation to wash the feet completely: Water must cover all parts of the feet during ablution, and it is not sufficient to merely wipe them or leave a part unreached by water, especially the heels. 2. Importance of thorough ablution: The Hadith indicates the necessity of ensuring water reaches all limbs of ablution. 3. The Prophet's (peace be upon him) compassion: He would linger to check on the conditions of the Companions and assist their weak ones. 4. The Companions' eagerness for prayer: They were keen to perform prayer on time despite their fatigue. 5. The Prophet's teaching and clarification of errors: He would clarify rulings of Sharia (definition) and not remain silent about errors. 6. Permissibility of raising one's voice in knowledge: It is permissible to raise one's voice when necessary for teaching, such as due to distance or a large gathering. 7. Repeating speech for knowledge: It is recommended to repeat a Hadith so that the listener understands it and the doubtful person becomes certain. 8. Warning against negligence: A Muslim must beware of negligence in matters that seem simple, as they may be great in the sight of Allah.
