It is narrated from Sayyiduna al-Sharid (may Allah be pleased with him), who said: The Prophet (peace and blessings be upon him) saw a man letting his lower garment hang down, so he (peace and blessings be upon him) went to him quickly, or hurried to him at a run, and said: "Raise your lower garment, and fear Allah." He said: I have bowed shins; my knee knocks. He (peace and blessings be upon him) said: "Everything Allah has created is good." The narrator said: After that, that man was never seen except that his lower garment reached halfway down his shins, or struck the middle of his shins.
