What did the Prophet (saw) and his companions do when their feet became thin during a Ghazwa?
 Narrated Abu Burda:                     Abu Musa said, "We went out in the company of the Prophet for a Ghazwa and we were six persons having one camel which we rode in rotation. So, (due to excessive walking) our feet became thin and my feet became thin and my nail dropped, and we used to wrap our feet with the pieces of cloth, and for this reason, the Ghazwa was named Dhat-ur-Riqa as we wrapped our feet with rags." When Abu- Musa narrated this (Hadith), he felt regretful to do so and said, as if he disliked to have disclosed a good deed of his.
