وَأَتِمُّوا الْحَجَّ وَالْعُمْرَةَ لِلَّهِ
Complete the pilgrimage and the umrah for Allah.
The verb atimmū demands completion. It can govern a person who has entered an act of worship, but does not alone settle the separate question whether beginning an umrah is independently obligatory for every person.
The duty to complete an initiated act and the duty to initiate it are distinct propositions. Establishing the second requires appropriate evidence beyond merely translating “complete” as though it meant “begin.”
