2. Sahl ibn Ziyad has narrated from Ahmad ibn Muhammad from Dawud ibn Sarhan who has said the following: “Abu ‘ Abd Allah , has said, ‘Without passing the twentieth day of the month of Ramadan Ttikaf is not valid.’ He (the Imam) then said that Ali ‘Alayhi al-Salam, would say, “I do not see Ttikaf, unless it is in Masjid al-Haram, Masjid of the Messenger of Allah, or a Jami‘ Masjid (central). It is not proper for one performing ’Ttikaf to go out of Masjid except for one’s urgent needs without which one cannot do, but then one must not sit down until one returns. The same rule applies to women.’””

3. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Hammad from al-Halabiy who has said the following: “Once abu ‘Abd Allah , was asked about ’Ttikaf. He (the Imam) said, ‘Without Masjid ’Ttikaf is not valid, only in Masjid like Masjid al-Haram, Masjid of the Messenger of Allah, Masjid al-Kufah or Masjid al-Jami‘ and you must fast in the time you are in the state of ’Ttikaf.’”

4. A number of our people have narrated from Ahmad ibn Muhammad from al-Husayn ibn Sa‘id from Fadalah ibn Ayyub from ‘Abd Allah ibn Sinan who has said the following: “He (the Imam) , has said, ‘One performing ’Ttikaf in Makkah can perform Salat (prayer) in any of its houses or Masjid; it is all the same.’”

5. Abu Ali al-Ash’ariy has narrated from Muhammad ibn ‘Abd al-Jabbar from Safwan ibn Yahya from Mansur ibn Hazim who has said the following: “Abu ‘Abd Allah , has said, ‘One who performs ’Ttikaf in Makkah can perform Salat (prayer) in any of its houses that he chooses, and one performing ’Ttikaf in other places cannot perform Salat (prayer), unless it is the Masjid which he has determined.’”
