The greatest factor which will increase or rather incur barakat and
blessings in ones sustenance is total obedience to Allah Ta’ala and His
Rasul (Sallallaahu Alayhi Wasallam).
As mentioned in a Hadith, disobedience and sin deprives and diminishes the
sustenance of a person. (Nasai, ibn Majah, Ahmed in his Musnad and Haakim in
his Mustadrak). Five times daily salaat is also a means through which Allah
Ta’ala causes blessings and increase in ones earnings. In the Ahaadith,
there are numerous deeds of piety mentioned which increase the sustenance of
a person e.g. upholding family ties and spending in the path of Allah. Nabi
(Sallallaahu Alayhi Wasallam) used to make the following Du’aa: Allahummak
fina bi halaalika an haraamika wa agnina bifadlika amman siwaak.
and Allah Ta’ala Knows Best
