Meaning
An imitator; one who follows a master or an authority rather than striking out on his own — in poetry, a follower of an established style.
Literally: one who does taqleed (imitation, following)
Usage & notes
Iqbal's whole ethic of khudi is set against the muqallid — the borrowed, second-hand self that imitates instead of becoming; he calls the seeker to originate, not to copy.
