The Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, then said: "The ghusl for entering the city of the Messenger (peace and blessings be upon him and his family) to perform an obligation or recommended act is a sunnah. The ghusl for entering Mecca for the same purpose is also a sunnah. The ghusl for visiting the grave of the Prophet (peace and blessings be upon him and his family) is a sunnah, as is the ghusl for visiting the graves of the Imams عليه السلام. The ghusl for entering the Kaaba is a sunnah, as is the ghusl for entering the Sacred Mosque (Masjid al-Haram) and the ghusl for participation in the act of mutual invocation (mubahalah)." These ritual baths have already been mentioned in the narration of Uthman ibn Isa from Sama’ah, as well as some in the narration of Muhammad ibn Muslim mentioned earlier. These narrations suffice without needing additional ones, Allah سبحانه وتعالى willing. The Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, also said: "The ghusl of repentance for major sins is a sunnah."
