Do they then only wait for the Hour,- that it should come on them of a sudden? But already have come some tokens thereof, and when it (actually) is on them, how can they benefit then by their admonition?
This verse asks whether those disbelievers and hypocrites (mentioned in
the previous verses) are waiting for the Final Hour, and whether they know that
it will come upon them suddenly and that they will not have time to repent and
remember God (Ṭ). Although there are many discussions regarding the signs or
portents of the Hour, the sign to which this verse refers is most likely the coming
of the Prophet, who is reported to have said, “I was sent like this in relation to
the Hour,” while pointing to his index finger and his middle finger (Mw, Q).
