«فَأَقِمْ وَجْهَكَ لِلدِّينِ الْقَيِّمِ»
So set your face toward the upright religion.
«أقم» and «القيم» are connected to the root **q-w-m**, sharing the semantic field of standing, establishment and uprightness. Their derived patterns differ while the fundamental root and related meaning remain.
That is the value of ishtiqāq as an ornament: several related forms activate a common semantic core. It does not require identical pronunciation, letter count and order in the way complete jinās does.
