How did Allah's Prophet Abraham prepare the fat roasted calf so quickly, even though the verse indicates that he "turned to his household and then brought it," and the "then" (fa) implies immediate sequence, while preparing a calf takes a long time?

Allah praised Abraham (peace be upon him) for his generosity and hospitality towards guests. He swiftly offered sustenance to his guests; the slaughtering, cooking, and serving followed in quick succession without delay. The letter "fa" (ف) in the verse signifies order and immediate succession.
