Seest thou one who forbids-
The words, may be applied generally to perverse
humanity, which seeks not only to rebel against Allah’s
Law, but also to prevent others from following it.
There may however be a reference here to Abu Jahl, an
inveterate enemy of Islam, who used in its early days to
insult and persecute the holy Prophet and those who
followed his teaching.
He used, in particular, to use shameful methods to
prevent the Prophet from going to the Ka’bah for
devotions, and forbid any who came under his influence,
from offering prayers or performing devotions.
He was arrogant and purse-proud and met his end in the
battle of Badr.
