1. Islam, a person has to be a Muslim
2. Sound mind
3. Be at the age of discernment
5. The masjid should be one where congregational prayer is observed.Allah says, “while you are in I’tikâf (i.e. confining oneself in a mosque for prayers and invocations leaving the worldly activities) in the masjids.” [ Al-Baqarah 187 ]
In reference to the authentic hadeeth collected in Al-Bayhaqi in his Sunnan. “ There is no Itikhaf except in three Masjids.” Refers to a complete itikaf however it is okay to perform Itikaf in other than Masjid Al-Aqsa, Haram Mecca and the Prophet’s masjid.
