The Messenger of Allah (ﷺ) forbade that a man should wrap himself completely in a garment with his hands hidden it, or sit in a single garment with his hands round his knees.
Sunan Abi Dawud Book 34, Hadith 62
← Previous Hadith The Messenger of Allah (ﷺ) forbade wearing clothes in two styles: that a man sits in a single garment with his hands round his knees and uncover his private parts towards heaven and that he wears his garment while one of his sides is uncovered, and puts the garment on his shoulders.

Sunan Abi Dawud Book 34, Hadith 61 Next Hadith → I came to the Messenger of Allah (ﷺ) with a company of Muzainah and we swore allegiance to him. The buttons of his shirt were open. I swore allegiance to him and I put my hand inside the collar of his shirt and felt the seal.

'Urwah said: I always saw Mu'awiyah and his son opening their buttons of the collar during winter and summer. They never closed their buttons.
