Suppose you use a horse for transportation as people have done in the past. One of your friends invites you to his house and you get there by riding your horse. Now, what would happen if your friend totally ignores you and starts feeding and looking after the horse only? You will feel confused as yourself, the rider, was suppose to be the guest, not the horse that you rode on.
The above situation sounds abnormal but that is exactly what we are doing today. Allah has given us a body and a soul. The soul rides on the body to pass through this world. In other words, the body is like the horse and the soul is like the rider of the horse. Today, we are continuously busy in feeding and looking after the body but totally ignored the well being of our souls. As a result, our souls have become so weak without the spiritual food that it is not strong enough to even push us to go to the Masjid or wake up for Fajr prayer. Thus, it is essential that we strengthen our soul with the spiritual food as shown by Islam, such as keeping the company of the pious, recitation of the Holy Quran, Dhikr of Allah and contemplating over the Greatness of Allah.
