and the fifth time, that God's curse be upon him if he is telling a lie.

And the fifth (oath) (should be) that they solemnly invoke the curse of God on themselves if they tell a lie.

And yet a fifth, invoking the curse of Allah on him if he is of those who lie.

And the fifth (time) that the curse of Allah be on him, if he is of those who lie.

And the fifth [oath will be] that the curse of Allah be upon him if he should be among the liars.
