الموطأ




الموطأ لامام الائمة وعالم المدينة 
مالك بن انس رضى الله عنه

وقد اشتمل كتاب الموطأ فى اول تاليفة على ماذكره الكيا الهراسى فى تعليقه فى الاصول على تسعة الاف حديث ثم لم يزل يتنقى منه ، حتى رجع الى سبعمائه . واخرج ابو الحسن بن فهر فى فضائل مالك  عن عتيق بن يعقوب ، قال : وضع مالك الموطا على نحو عشره الاف حديث فلم يزل ينظر فيه كل سنه ويسقط منه حتى بقى هذا .
