Hadith 689
It is narrated from Sayyiduna Anas (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings be upon him) intended to relieve himself, he would not lift his garment until he was close to the ground. Imam Darimi Abu Muhammad (may Allah have mercy on him) said: This is also among the etiquettes of relieving oneself and is similar to the hadith of Mughira.
