God created the first man, Adam, and initially inhabited him in the garden of Paradise. He was told that he could live in Paradise with full freedom but with only one condition. In Paradise he was forbidden from approaching a particular tree or eating of its fruit. (THE QURAN 2: 35)
This was the original forbidden tree of Adam's motherland. However, according to the Quran, Adam was unable to remain patient, and he ate from the fruit of the forbidden tree (THE QURAN 20: 121). He failed the ‘test’ that God had given him in Paradise. As a result of this action, he was banished from the garden of Paradise and sent to live on earth.
In Paradise there was only one forbidden tree; in this world there is a jungle of ‘forbidden trees’.
Nevertheless, as far as the test for man is concerned, it remains the same here on earth also. The difference between the two is that in Paradise there was only one forbidden tree, and in this world there is a jungle of ‘forbidden trees’. The return to Paradise for man will only be on the condition that he does not partake of the fruit of the forbidden trees. Now, for man to fulfill this condition, he has to be extremely cautious, because while originally he had to avoid only one tree, here it is necessary for him to refrain from a jungle of forbidden trees.
An account of things which are forbidden can be found in the Quran and Hadith. In the present age, the list of such things which lead man astray from the straight path has become very extensive. Such a comprehensive list of forbidden things cannot be compiled. Man has to now live very cautiously in this world. Whenever he comes across something that is a distraction from the straight path, he should immediately recognize it and shun it completely.
In this world, all such things take the place of a ‘forbidden tree’ that make man forget God and neglect the accountability of the Hereafter. Only the one who examines his life and continuously introspects will be able to save himself from these ‘forbidden trees’.
