1. A number of our people have narrated from Sahl ibn Ziyad from al-Hassan ibn Mahbub from ‘Umar ibn Yazid who has said the following: “I once asked abu ‘Abd Allah (a.s.), about performing Ttikaf in a certain Masjid of Baghdad. He (the Imam) said, ’Without a Masjid in which Salat (prayer) in congregation is held behind a just Imam, Ttikaf is not valid. It is not harmful to do Ttikaf in Masjid of al-Kufah, in al- Basrah, in al-Madinah or Makkah.’”

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.’””
