The phrase “ghayr makfiyy” (“never adequately recompensed”) has been transmitted in two forms: with and without a hamza.
The reading with a hamza has been judged erroneous, since the word is a passive participle. It is derived either (2) from kifāyah (sufficiency), in which case its proper form is ghayr makfiyy, like marmiyy and maqdiyy; or from mukāfāh (recompense), whose passive participle is mukāfā (3), like murāmā from rāmāhu and musā‘ā from sā‘āhu.
Alternatively, it is derived from kafa’tu al-inā’—with a hamza—meaning “I overturned the vessel.” Its passive participle would then be makfū’, like maqrū’ from qara’tu (“I read”) (4).
