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.’” شهور - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (16/428))
