2. Muhammad ibn Isma‘il has narrated from al-Fadl ibn Shadhan from Safwan ibn Yahya from Mansur ibn Hazim from Sulayman ibn Khalid who has said the following: “I once asked abu ‘ Abd Allah , on how many nights should one take a shower in the month of Ramadan?’ He (the Imam) replied, ‘It is on the nineteenth, twenty- first and twenty-third nights.’ I then said, ‘What if even this much becomes difficult for me?’ He then said, ‘Take a shower on the twenty- first and twenty-third nights.’ I then said, ‘What happens if this becomes difficult for me?’ He (the Imam) said, ‘Now it is enough.’”

3. Safwan ibn Yahya has narrated from ‘Is ibn al-Qasim who has said the following: “I once asked abu ‘Abd Allah , about the night during which one can appeal before Allah for one’s needs when it is the time for a shower. He (the Imam) replied, ‘It is at the beginning of the night, or if you like, at the end of the night as you wake up.’ I then asked about al-Qiyam (rising up) (for salat [prayer]). He said, ‘You may rise in the beginning or toward the end of the night.’”

4. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn and Safwan ibn Yahya and Ali ibn al-Hakam from al-‘Ala’ ibn Razin from Muhammad ibn Muslim who has said the following: “One of the two Imam, ‘Alayhim al-Salam, has said, ‘One should take a shower in the nineteenth, twenty-first and twenty-third nights of the month of Ramadan. ’Amir al-Mu’minin , sustained a mortal wound by an assassin in the nineteenth night. He (the Imam) passed away on the twenty-first night of the month of Ramadan. A shower should be taken at the beginning of the night and it is enough until the end of the night.”
