Sahih Bukhari Volume 5, Book 64, Hadith 4130

حَدَّثَنَا مُحَمَّدُ بْنُ الْعَلاَءِ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ بُرَيْدِ بْنِ عَبْدِ اللَّهِ بْنِ أَبِي بُرْدَةَ، عَنْ أَبِي بُرْدَةَ، عَنْ أَبِي مُوسَى ـ رضى الله عنه ـ قَالَ خَرَجْنَا مَعَ النَّبِيِّ صلى الله عليه وسلم فِي غَزَاةٍ وَنَحْنُ سِتَّةُ نَفَرٍ بَيْنَنَا بَعِيرٌ نَعْتَقِبُهُ، فَنَقِبَتْ أَقْدَامُنَا وَنَقِبَتْ قَدَمَاىَ وَسَقَطَتْ أَظْفَارِي، وَكُنَّا نَلُفُّ عَلَى أَرْجُلِنَا الْخِرَقَ، فَسُمِّيَتْ غَزْوَةَ ذَاتِ الرِّقَاعِ، لِمَا كُنَّا نَعْصِبُ مِنَ الْخِرَقِ عَلَى أَرْجُلِنَا، وَحَدَّثَ أَبُو مُوسَى بِهَذَا، ثُمَّ كَرِهَ ذَاكَ، قَالَ مَا كُنْتُ أَصْنَعُ بِأَنْ أَذْكُرَهُ‏.‏ كَأَنَّهُ كَرِهَ أَنْ يَكُونَ شَىْءٌ مِنْ عَمَلِهِ أَفْشَاهُ‏.

Narrated By 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.
