I’ve always wondered what Mohammad’s last words were...
"τετελεσται"
(perfect tense)
Jesus on the cross but his last words before his ascension in Acts 1:
7 He said to them: It is not for you to know the times or dates the Father has set by his own authority. 8 But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth.
