Prohibition of isbal (letting garments hang below the ankles) for men and explanation of the punishment for its perpetrator

Question:
We have here in one of the mosques a Friday preacher who delivers lessons before the Friday sermon. On one Friday, he spoke and said that letting the trousers and garments hang down is permissible and there is nothing wrong with it, and that shortening or raising them above the ankles or to the middle of the calves is a religious innovation (bid'ah). So what do you advise this preacher? May you be rewarded, may Allah reward you with good.

Answer:
This is his argument. If what I was absent from is true, he has erred and is ignorant. May Allah guide him and grant him beneficial knowledge, faith, and [guidance for] the Muslims. The correct view is that isbal (letting garments hang below the ankles) is not permissible. [It is prohibited] below the ankles in the case of the man, whether in trousers, in a shirt, in a vest, or in an izar (loincloth), and this is the right of the man.
And other than the Prophet (peace and blessings be upon him) in the authentic hadith that al-Bukhari narrated: "Whoever drags his garment out of arrogance from the ankles down, he is in the Fire." And his saying (peace and blessings be upon him): "Three whom Allah will not speak to, nor look at, nor purify on the Day of Resurrection: meaning that his garment does not bear fruit, meaning the one who gives and has given, does not spend his goods with a comprehensive letter, the harm of Imam Muslim in his Sahih. And this is from the two hadiths that are effective in prohibiting the invalidation. Because it is from the major sins. Or it is obligatory for every Muslim to beware of that. And if the dragging is for the sake of arrogance, it becomes greater and more immense in sin. Due to the saying of the Prophet (peace and blessings be upon him): So if he does it out of arrogance and vanity, the sin is greater. As for the washing of the whip above the ankle, and it is touching the lower leg, this is the Sunnah, as it came in the Sunnah of the Prophet (peace and blessings be upon him) regarding the man. As for the woman, the Sunnah for her is to cover her feet, unless she has a shawl or impurity, then there is no harm. And if so, the Sunnah for her is to cover her clothes until her feet are hidden.
