When the horses are set forth for the purpose of jihad they gallop and pant at full pace making sounds of heavy breathing as their hooves strike the ground, they strike up sparks of fire as the hooves connect with the rocks stirring up clouds of dust as they penetrate into the hearts of the enemy lines.
Allah SWT states how ungrateful humankind is towards their Lord Allah SWT and that humans attest and also bear witness to this that they deny the favours of Allah SWT not seeking that which is permissible and having an aversion towards what is good and just.
People become severe in their love for wealth meaning being in extreme for worldly gains and also being stingy and miserly when it comes to the acquisition and desire for more wealth. This extreme behavior towards love of wealth and competing with one another leads to destruction of not just people but entire nations.
It is far better and greater to seek that which is in the hereafter preparing for the day of judgement when all the contents of the graves will be spilled out and all the secrets of heart will be laid bare. Allah SWT is well acquainted with what a person strives for and nothing is hidden from Allah SWT.
So do not deny the many blessings and favours of Allah SWT. Seek to prepare for the hereafter which is more enduring and far more rewarding as this worldly life is fleeting, temporary and the only value is seeking the face of Allah SWT where a person prepares for meeting with Allah as the day of Judgement when everything will be apparent and laid bare. Allah is well aware of what the people are doing is All Aware of every soul and on the day of Judgement when a person will be recompensed for the good or evil they have done for their time on earth and there will be no injustice done by Allah SWT and the people will surely know why they are being sent either to the hellfire or to paradise and it will be completely justified.
