1. Muhammad ibn ’Isma‘il has narrated from al-Fadl ibn Shadhan from Safwan ibn Yahya and Ibn Abi ‘Umayr from Mu‘awiyah ibn ‘Ammar who has said the following: “I heard abu ’Abd Allah (a.s.), state this Hadith: ‘There is Ghusl (bath) because of sexual relations, there is Ghusl (bath) on Friday, on the two ‘Ids, at the time of assuming the state of ‘Ihram, there is Ghusl (bath) when entering Makkah and al-Madinah. There is Ghusl (bath) on the day of ‘Arafah, (9th of the month of Dhul-Hajjah) on the day of one’s visiting the House (al-Ka‘bah) for entering al-Ka‘bah, in the nineteenth, twenty first, twenty-third nights of the month of Ramadan and for touching a dead body.’”

2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Muhammad ibn ‘Uthman ibn ‘Isa from Sama‘ah who has said the following: “I once asked abu ‘Abd Allah (a.s.), about Ghusl (bath) on Friday. He (the Imam) said, ‘It is obligatory, regardless, if one is on a journey or at home except that women are exempt on a journey due to scarcity of water.’ He (the Imam) said, ‘Ghusl (bath) because of sexual relation is obligatory as well as because of Hayd (menses) when bleeding stops. It is obligatory for al-Mustahazah (irregular Hayd (menses)) if blood passes through the piece of cotton, which (she has) placed in her urethra. In such case she must take Ghusl (bath) for every two Salah (prayer) and for the morning Salah (prayer). If blood does not pass through the piece of cotton, there is once Ghusl (bath) only every day and Wudu’ for every Salah (prayer). Ghusl (bath) is obligatory because of al-Nifas (childbirth). Ghusl (bath) of newborn is obligatory. Ghusl (bath) of a dead body is obligatory. There is Ghusl (bath) for visiting (al-Ka‘bah), for entering the House, and for pleading for rainfall. It is preferable to take Ghusl (bath) in the first night of the month of Ramadan. Ghusl (bath) in twenty-first and twenty-third nights of the month of Ramadan is Sunnah that one should not ignore because one of them is the night of al- Qadr. Ghusl (bath) on the day of al-Fitr (the first day of the month of Shawwal), on the day of al- Adha’ (tenth of the month of Dhul Hajjah) is of the Sunnah. I do not like to ignore it. There is Ghusl (bath) for Istikharah. It is preferable to take Ghusl (bath) to perform acts of worship during the three nights of the month of Ramadan; the nineteenth, twenty- first and twenty-third nights.’”
