It was narrated that Hudhaifah said: “The Messenger of Allah صلی اللہ علیہ وآلہ وسلم said: ‘The Izar should come to middle of the shins and the calf. If you insist, then a little lower, and if you insist, then a littlen further down, but the Izar has no right to (come to) the ankle.” This is the wordings of Muhammad.
