[Say, O Prophet:6
] "Would that you two turn unto God in repentance, for the hearts of both of you have swerved [from what is right]!7
And if you uphold each other against him [who is God's message-bearer, know that] God Himself is his Protector, and [that,] therefore,8
Gabriel, and all the righteous among the believers, and all the [other] angels will come to his aid."
Although in the sequence the Prophet is referred to in the third person, it is obvious that it is he who is commanded through revelation to speak thus to his wives Hafsah and 'A'ishah (see note ); hence my above interpolation.
Referring to Hafsah, who betrayed the Prophet's confidence, and to 'A'ishah, who by listening contributed to this betrayal (see note  above).
Lit., "after that", i.e., in consequence of the fact that God Himself protects him.
