It is narrated from Sayyidah Aisha (may Allah be pleased with her) that the Messenger of Allah (peace be upon him) rubbed and cleaned the spittle stuck to the qiblah side of the mosque. In the narration of Abu Kuraib, it is mentioned that the Prophet (peace be upon him) scraped and cleaned spittle, nasal discharge, or phlegm from the direction of the qiblah.
