It is narrated from Umm Walad Ibrahim bin Abdur Rahman bin Awf that she came to Umm al-Mu'mineen, Sayyida Umm Salamah (may Allah be pleased with her), and said: "I keep my garment long and sometimes pass over dirty ground (i.e., the hem becomes impure)." Sayyida Umm Salamah (may Allah be pleased with her) said: The Messenger of Allah (peace and blessings be upon him) said: "The earth that comes after that impure earth purifies it." The narrator said: I asked Imam Darimi: Is this your verdict? He said: I do not know.
