Abu Musa Al- Ash'ari (May Allah be pleased with him) said: "Six of us accompanied Messenger of Allah (ﷺ) in an expedition. We had one camel with us; we rode it in turn. Our feet got injured and my nails also fell out. We wrapped up our feet in rags; and because of this the campaign came to be known as Dhat-ur-Riqa' (the Campaign of Rags)." Abu Burdah (May Allah be pleased with him) says: Abu Musa reported this Hadith but regretted having done so. He said, "Would that I had not mentioned it!" He said so because he disliked to disclose anything concerning his deeds.
