Allah alone has the Power and Authority over Loss and Gain.

Allah alone has the Power and Authority over Loss and Gain.

The Holy Quran teaches that Allah has the
supreme authority over all things including the loss
and gains that man encounters in his life, and that man
should trust only Allah and should believe that Allah
alone has the authority to effect loss and gains in his
life.
“They have taken, besides Him (Allah), gods that can
create nothing but are themselves created; that have
no control of hurt or good to themselves; nor can they
control death nor life nor resurrection.” (25:3)
In another place, it is stated:
“Do not call on any other than Allah that will neither
profit you nor hurt you; if you do so, behold, you shall
certainly be of those who do wrong. If Allah do touch
you with hurt, there is none can remove it but He; if He
do design some benefit for you, there is none can keep
back His favour; He causes it to reach whomsoever of
His servants He pleases. And He is the Oft-Forgiving,
Most Merciful.” (The Quran, 10:106-107)
Explaining the aforesaid Verses further, Prophet
Muhammad (peace be upon him) said:
“When you seek help, seek help only from Allah and
trust (him); if all people would like to benefit you they
would not be able to do so except that which Allah has
destined for you, and if all the people would like to hurt
or harm you, they would not be able to do so except that
which Allah has ordained for you.” (Tirmizi).
