The Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), narrates that she said: "O Messenger of Allah, you go into the toilet, yet (afterwards) nothing of the filth that comes out of you (peace and blessings be upon him) is seen?" He (peace and blessings be upon him) said: "O Aishah, do you not know that the earth swallows what comes out of the Prophets, so nothing of it is seen?"
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Sayyidah Aishah (may Allah be pleased with her) only with this chain, and Isma'il bin Aban is alone in narrating it."
