The expression "by God's leave" is to be understood, in this context, as "with God's help" or "by God's grace" (Zamakhshari, Razi). As so often in the Qur'an, the sudden change, within one and the same sentence, from the pronoun "We" or "I" to "He", or from "We" to "God", is meant to impress upon the listener or reader of the Qur'an the fact that God is not a "person" but an all-embracing Power that cannot be defined or even adequately referred to within the limited range of any human language.
