It is narrated from al-Qasim bin Muhammad (may Allah have mercy on him) that the Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), said: "People have said a great deal about the ritual bath (ghusl) on Friday, yet its beginning was in my house. (What happened was that) some people from the upper outskirts of Madinah (al-'Aliyah) came to the Messenger of Allah (peace and blessings be upon him) on a very hot day. They had come after working in their date-palm orchards and were wearing woollen garments, and when they entered, an unpleasant smell was coming from them. So the Messenger of Allah (peace and blessings be upon him) said: 'When it is this day, take a ritual bath.'"
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from al-Qasim bin Muhammad except Amr bin Yahya, nor from Amr except Isma'il bin Rafi', nor from Isma'il except al-Fadl bin al-Ala'; Muhammad bin Hisham al-Sadusi is alone in narrating it."
