Imam Maalik مالك بن أنس بن مالك بن أبي عامر · Clothing (Kitab Al-Libas)

Abu Amir or Abu Malik told me--I swear by Allah another oath that he did not believe me that he heard the Messenger of Allah (ﷺ) say: There will be among my community people who will make lawful (the use of) khazz and silk. Some of them will be transformed into apes and swine. Abu Dawud said: Twenty Companions of the Messenger of Allah (ﷺ) or more put on khazz. Anas and al-Bara' b. 'Azib were among them.

A robe containing silk was presented to the Messenger of Allah (ﷺ). He then sent it to me. I wore it and came to him. I saw him looking angry in his face. He then said: I did not send it to you to wear. He ordered me and I divided it among my women.

The Messenger of Allah (ﷺ) was brought some pieces of fine Egyptian linen and he gave me one and said: Divide it into two; cut one of the pieces into a shirt and give the other to your wife for veil. Then when he turned away, he said: And order your wife to wear a garment below it and not show her figure. Abu Dawud said: Yahya b. Ayyub transmitted it and said: 'Abbas b. 'Ubaid Allah b. 'Abbas

That he heard the Messenger of Allah (ﷺ) say: When a skin is tanned, it is pure.

The Messenger of Allah (ﷺ) forbade that a man should put on sandals while standing.

It is part of the Sunnah that when a man sits down, he should take off his sandals and place them at his side.
