Ibrahim bin Abdur Rahman bin Awf’s freed slave woman (Hamidah), may Allah have mercy on her, narrates: I used to let the hem of my cloak hang low and would pass through both clean and unclean places, so I asked Lady Umm Salamah, may Allah be pleased with her, about this. She replied: I heard the Messenger of Allah, peace and blessings be upon him, say: After that, the (pure) earth will purify it.
