Musannaf Ibn Abi Shaybah 26854 — What is disliked of clothing

Abdullah bin Buraydah narrates from his father, from the Prophet (peace and blessings be upon him), that he (peace and blessings be upon him) forbade two kinds of dress and two ways of sitting. The two kinds of dress are that you pray in trousers with nothing on you besides them, and that a man prays in a single garment which he does not wrap across his shoulders. The two ways of sitting are that a man sits with his waist and shins bound in one garment so that his private parts can be seen, and that a man sits between the sun and the shade.
