Chapter 317 | The meaning of haqila, muzabana, ‘araya, mukhabarat, mukhadhara, munabadha, mulamasa, the selling of pebble and other things that were declared forbidden
وكره صلى الله عليه وآله الشكال في الخيل. يعني أن يكون ثلاث قوائم منه محجلة و واحدة مطلقة. وإنما اخذ هذا من الشكال الذي يشكل به الخيل شبه به لان الشكال إنما يكون في ثلاث قوائم وأن يكون الثلاث مطلقه ورجل محجلة وليس يكون الشكال إلا في الرجل ولا يكون في اليد.
He, Allah’s blessings be upon him and his Family, also disliked shikal in horses. It means that three standing legs of a horse have anklets and that one is free. It stems from shikal, that which a horse is being decorated with. It was likened to it because shikal is only performed in three standing legs while the three are free and one has anklets. Shikal is not performed except in the foot, and it is not performed to a hand.
