(Allah confirmeth those who believe) in Muhammad (pbuh) and in the Qur'an; it is also said that this means: those who believed were on the day of the Covenant with a good disposition of the soul, and these are the felicitous people, (by a firm saying) the testification that there is no god but Allah (in the life of the world) so that they do not go back on it (and in the Hereafter) i.e. in the grave when asked about it, (and Allah sendeth wrong-doers) the idolaters (astray) from the testification of there is no god but Allah in the life of this world, so that they do not say it with a good disposition of the soul, nor in the grave nor when they come out of it. These are the people destined for damnation. (And Allah doeth what He will) whether it is sending astray or holding people firm; it is also said: (And Allah doeth what He will) about turning away Munkar and Nakir.
