1692/1 - Ibn ‘Umar (may Allah be pleased with him and his father) reported: “The Messenger of Allah (may Allah’s peace and blessings be upon him) forbade riding the camel which feeds on dung.” [Narrated by Abu Dāwūd, with an authentic Isnād]
--
1) It is disliked to ride camels that feed on dung and impure things. This is meant to protect the rider from impurity.
2) The Shariah instructs us to avoid impurities. Thus, it wants to honor us and protect our health.
