Earning a halal rizq
Even if you pray 5 times a day, fast the whole month of Ramazan, perform haj and umrah but you earn through haram like being unfair in business especially while selling products, cheating your bosses and managers and doing fraud whether in business or in bank accounts then you are earning haram rizq and will be punished on the day of judgment for it. Betraying your bosses and managers like for example not following the timings, eating from company's money and taking extra money as salary and money laundering and making false excuses for being absent like going on vacation while lying that you are ill are example of haram rizq. In the end what I would like to say is that Allah has given us huge rewards both in this world and the hereafter if we earn through halal means.
