It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) used to perform ghusl (ritual bath) with the water left over by Sayyidah Maymunah (may Allah be pleased with her). The narrator of the hadith, Abdur Razzaq, says that in fact, I had asked my teacher about the issue of two persons in a state of major ritual impurity (janabah), a man and a woman, performing ghusl with the same water, so he narrated this hadith to me.
