Then, it is to fast from even witnessing the fast of mā siwā (all that is other than Allah). Through this fast, the fiṭr (innate disposition) emerges with the aid of contemplation (tafakkur). In the ḥajj (pilgrimage), it is for the qalb (the heart) to ascend to the maqām (spiritual station) of isolation from the nafs (the lower self), to remove the nafs from its caprices, and to annihilate all affiliations other than (Allah). In summary, in all these, there is the secret of purifying from mā siwā, turning one's himma (spiritual aspiration) toward the Real (al-Ḥaqq), abandoning every beloved other than Him, fasting from witnessing the fast, and making pilgrimage to the realm of contemplation (mushāhada). Thus, this third field pertains to the gaze of the one who looks toward ihsan (spiritual excellence). (Ravza, 196)
