Maliks Muwatta Book 48, Hadith Number 17.

Section : Ways of Dressing.

Yahya related to me from Malik from Abu’z-Zinad from al-Araj that Abu Hurayra said, “The Messenger of Allah, may Allah bless him and grant him peace, forbade two sales. Mulamasa, in which a man is obliged to buy whatever he touches without any choice in the matter, and munabadha, in which two men throw their garment to each other without either seeing the other’s garment. He also forbade two ways of dressing. One in which a man sits with his legs drawn up to his chest wrapped in one garment that does not cover his genitals, and the other in which a man wraps a single garment over one arm and shoulder restricting them.”
