Allah Blesses the Muslim Economy As Long As the Muslims Preserve His Law

Whenever Muslims sincerely preserve Allah's
Commandments and recommend one another to preserve
the righteous Islamic Law, then Allah will make their
conditions better and will bless their wealth and work.

Allah will also help them achieve their goals and acquire
safety from their enemies.
Allah, the Exalted, the Most Honored, asserted all
these meanings, when He said,

{O you who believe! Be afraid of Allah, and be with those
who are true (in words and deeds)}[9:119],


{O you who believe! Stand out firmly for justice, as
witnesses to Allah, even though it be against yourselves, or
your parents, or your kin, be he rich or poor, Allah is a
Better Protector to both (than you). So follow not the
lusts (of your hearts), lest you may avoid justice, and if you
distort your witness or refuse to give it, verily, Allah is Ever
Well-Acquainted with what you do}[4:135],

{O you who believe! Stand out firmly for Allah and be just
witnesses and let not the enmity and hatred of others make
you avoid justice. Be just: that is nearer to piety, and fear
Allah. Verily, Allah is Well-Acquainted with what you
do}[5:8],
{And make ready against them all you can of
power}[8:60],
and, {O you who believe! Take your precautions}[4:71].
