Ruh bin Zinba’ says that once he went to meet Sayyiduna Tamim Dari (may Allah be pleased with him). Upon arrival, he saw that he himself was cleaning barley grains for his horse, even though his family members were present there. Ruh said,“Can none of them do this work?”He replied,“Why not, but the thing is that I heard the Prophet (peace and blessings be upon him) say: ‘Whoever among the Muslims cleans barley grains for his horse and then feeds them to it, for every grain a good deed will be written for him.’”
