Musnad Ahmad Hadith 19542

Shaqiq (may Allah have mercy on him) says that once I was sitting with Abu Musa Ash'ari (may Allah be pleased with him) and Abdullah bin Mas'ud (may Allah be pleased with him). Abu Musa (may Allah be pleased with him) said, "Did you not hear this statement of Ammar (may Allah be pleased with him): Once the Noble Prophet (ﷺ) sent me on an errand. During the journey, ghusl became obligatory upon me, but I did not find water, so I rolled in the earth as animals do. Then I presented myself before the Noble Prophet (ﷺ) and mentioned this incident. The Noble Prophet (ﷺ) said, 'It would have been sufficient for you to do just this.' Saying this, the Noble Prophet (ﷺ) struck his hand on the earth, then joined both hands together, and wiped his face."
