Love is a thing that burns a person’s base life and transforms them into a new and purified individual. Then, the person in question sees that which previously they could not see, and hears that which previously they could not hear. Hence, where God Almighty has prepared a spiritual feast of divine bounty and grace for man, He has also blessed man with the capacities that are needed to benefit from it. If God Almighty had granted man the relevant capacities but not the means, or if God had provided the means but no capacities to man, even this would have been a failing. But no, this is not the case. Allah the Exalted has granted abilities to man, as well as the means. Similarly, on the one hand, God Almighty provides man with bread, and on the other hand, He has given man eyes, a tongue and teeth, and He has put a man’s stomach, liver and intestines to work, and the proper functioning of all these things depends on food. If man consumed nothing, how would the heart be fuelled with blood and how would the body produce chyle?
In the same manner, first and foremost, God Almighty has showered His grace upon us and sent the Holy Prophet, peace and blessings of Allah be upon him, with a complete religion like Islam, and made him the Seal of the Prophets, and bestowed upon us a perfect book like the Holy Quran, which is the Seal of the Books. Now, until the Resurrection, neither shall any other book be sent, nor shall any other Prophet bring a new law.
Then, if we do not employ our faculties of reflection and contemplation, and if we do not advance towards God Almighty, how indolent, slothful and ungrateful would we be?
