One of the commandments of the Qur’an is given in the chapter Al-Ahzab (The Confederates) in these words: Believers, remember God with much remembrance. (33:41)
According to this Qur’anic verse, believers must remember God very much, every day and every moment. This is the most important teaching of the Qur’an, and it is also the highest form of worship. One who does this will be blessed with the greatest reward by God Almighty. What is much remembrance of God? It is not in the sense of repetition of some word but in the sense of thinking. Much remembrance, or Zikr-e-Kathir, is not a kind of lip service. It is rather a high kind of intellectual activity. Much remembrance is a sign of deep discovery of God. This chain reaction of Zikr will enhance your realization and discovery of God. It will enhance your relationship with God. Remembering God much is the result of a chain reaction in a person’s thinking process, that is, a series of thoughts in which each thought causes the next one. Zikr-e-Kathir, or much remembrance, is a result of creative thinking. It is a product of a prepared mind. If you are a prepared mind, then your mind is bound to be triggered at every experience or observation. You will start discovering one item after another of God-realization. In this way, a chain reaction will be initiated in your mind.
It is this intellectual activity that is called in the Qur’an Zikr-e-Kathir. For example, if it is raining, a believer will very soon present his thankfulness, that is, acknowledgment to God. Then he will start thinking further: what caused the downpour? He will discover the natural processes that resulted in rain. He will think that when the water was in the ocean, it was salty, but when it took the form of a downpour, it turned into freshwater. So step by step he will discover how God created various processes which finally provided him water to drink. This is an example of a chain reaction in thinking, and through this chain reaction, you begin to discover items of realization of God. If you are a prepared mind, then this process will continue without limit. According to the Qur’an, believers are given a unique blessing, that is, they are able to add faith to their faith. (48:4) This is not a mysterious phenomenon, it is a direct result of the above kind of chain reaction. This chain reaction of Zikr is very important for personality development. A believer increases his divine spirituality through this process.
