The Meaning of Ar-Rajim

Ar-Rajim means, being expelled from all types of righteousness. Allah said,
(And indeed We have adorned the nearest heaven with lamps, and We have
made such lamps Rujuman (as missiles) to drive away the Shayatin
(devils)) (67:5).
Allah also said,
(Verily, We have adorned the nearheaven with the stars (for beauty).
And to guard against every rebellious devil. They cannot listen to the
higher group(angels) for they are pelted from every side. Outcast, and
theirs is aconstant (or painful) torment. Except such as snatch away
something by stealing, and they are pursued by a flaming fire of
piercing brightness) (37:6-10).
Further, Allah said,
(And indeed, We have put the bigstars in the heaven and We beautified
it for the beholders. And We have guarded it (near heaven) from every
Shaytan Rajim(outcast Shaytan). Except him (devil) who steals the
hearing then he is pursued by a clear flaming fire.) (15:16-18).
There are several similar Ayat. It was also said that Rajim means, the
person who throws or bombards things, because the devil throws doubts
and evil thoughts in people's hearts. The first meaning is more
popular and accurate.
