Absolute Comfort,without Hardship, Is not Possible in the World:
Man Must be Prepared to Endure Hardships
The oath and its subject makes plain to man that his desire to live peacefully and comfortably in this world, without enduring any hardship, is a silly idea and false notion, which is not possible to happen. Therefore, it is necessary for difficulty, hardship, distress and affliction to befall every person. Since they are bound to befall, a wise person should be in readiness to work hard for something that may help him for an eternal life. The only factor that will help him for this is faith and obedience to the Truth.
Then, after describing a few of the ignorant disbeliever's qualities, the following verse says about an unbeliever: أَيَحْسَبُ أَن لَّمْ يَرَهُ أَحَدٌ (Does he think that no one has seen him?...90:7) that is, his evil deeds. He should realise that his Creator watches every action of his.
أَلَمْ نَجْعَل لَّهُ عَيْنَيْنِ وَلِسَانًا وَشَفَتَيْنِ وَهَدَيْنَاهُ النَّجْدَيْنِ
(Did We not make for him two eyes, and a tongue and two lips, and showed him the two ways?....90:8-10)
The word najdain is the dual form of najd which means an elevated or conspicuous road. The word najdain signifies the two high and conspicuous ways of good and evil, or of success and destruction. The preceding verse pointed out the ignorance and heedlessness of man. He thinks that Allah has no power over him, and that there is no one watching over his actions. The current verse mentions a few of the organs and abilities that Allah has endowed him with. If he reflects carefully on these endowments, he will appreciate His infinite wisdom and power within himself. He has a pair of eyes. The optic nerves and tissues are rather delicate. They send nervous impulses to the brain when stimulated by light rays from external objects. The structure of the eye itself is most delicate. Each eye consists of a hollow, spherical capsule [eyeball], made up of several layers and structures. It is set into a socket in the skull, and is protected by eyelids and eyelashes, and eyebrows. It works like an automatic machine. When a harmful object is seen coming from the front, the eyelids close on their own. The eyelashes block the dust from getting into the eyes. The eyebrows help keep things away from falling into the eyes directly from top. The facial bones, especially the orbit [eye socket and the cheek bones], protect the eye, if one were to fall on one's face or something were to fall on the face.
The second gift that man is endowed with is the 'tongue'. This organ the articulator is the most amazing and important creation. It is the long piece of flesh fixed to the bottom of the mouth that can represent thoughts of the heart, the automatic and mysterious machine. The heart works in an amazing way. A thought occurs in the heart, the brain interprets it, and prepares appropriate topic and words. The words are uttered by the tongue. Such a complex task is performed so swiftly that the listener does not even realise how many systems have worked before the distinguishable sounds, letters and words were uttered. Nature has equipped man with two lips that play an important role in articulating the different sounds, letters and words. Nature has made the tongue such a swift-working articulator that within half a minute it may utter a word which may take him out from Hell and admit him into Paradise, as the word of faith, or may endear him to his enemy in the world, as by seeking forgiveness of his shortcomings. The same tongue within the same short span of time may take him to Hell, as by uttering the word of disbelief, or may make him his biggest enemy who was previously his closest friend, as by using obscene language against him. The tongue has many benefits as well as many ways of destruction. It is a double-edged sword that can operate against an enemy, and it can also cut one's own throat. Therefore, Allah has kept it covered within the case of two lips. Probably, this is the reason why the pair of lips is mentioned. The Creator Who has endowed man with tongue has equipped him with a pair of lips in order to protect it. Therefore, he should be careful in its use. He should not unsheathe it unnecessarily. Allah has equipped him with a pair of eyes, a pair of lips and a tongue, and has equipped him with the ability to distinguish good from evil and right from wrong, thus:
