Mishkat al-Masabih

Sa'id b. al-Musayyib reported God’s Messenger as saying, “A pledge does not become lost to its owner when he does not redeem it in time. Any increase in its value goes to him and any loss must be borne by him.” Shafi'i transmitted it in mursal form, and something similar or something with a similar meaning with no discrepancy is transmitted on the authority of Abu Huraira with a fully connected isnad.
