[Pooya/Ali Commentary 72:18] Aqa Mahdi Puya says: Masjid means a place where one lays or bends with face on the ground in humble reverence-prostration. Figuratively it is used to refer to a place of worship. According to the Ahl ul Bayt, in this verse, masajid (plural of masjid) also refer to the parts of the body which are used in prostration-palms, knees, feet (toes) and forehead. Imam Muhammad bin Ali at Taqi advised the Abbasi caliph not to cut the portion of the hands of a thief above the four fingers, because the palms are used in the act of prostration.
