Someone asked Imam Zuhri, may Allah have mercy on him: Is it obligatory to perform ghusl (ritual bath) on Friday? He narrated with his chain of transmission from Sayyiduna Ibn Umar, may Allah be pleased with them both, this hadith: I heard the Prophet, peace and blessings be upon him, say, "Whoever among you comes for Friday (prayer), he should perform ghusl." And Tawus says: Once I asked Sayyiduna Ibn Abbas, may Allah be pleased with them both, that people think the Prophet, peace and blessings be upon him, said: "Even if you are not in a state of janabah, still perform ghusl on Friday, wash your head, and apply perfume"? Sayyiduna Ibn Abbas, may Allah be pleased with them both, said: As for perfume, I do not know about that, but the matter of ghusl is correct.
