Iʿtikāf is one of the recommended (mustaḥabb) ritual acts of worship (ʿibādāt) that becomes obligatory (wājib) by means of a vow (nadhr), covenant (ʿahd), oath (qasam), or suchlike. A valid iʿtikāf is when one stays in a mosque with the intention of attaining proximity to Allah (qaṣd al‐qurbah). And the recommended precaution (al‐iḥtiyāṭ al‐mustaḥabb) is that the stay should take place with the intention of performing ritual acts of worship, such as prayers (ṣalāh), and supplications (duʿāʾs).
