In the Name of Allah, the Most Gracious, the Most Merciful.
ن
(Nun), is like Allah's saying,
ص
(Sad), and Allah's saying,
ق
(Qaf), and similar to them from the individual letters that appear at the beginning of Qur'anic chapters. This has been dis- cussed at length previously and there is no need to repeat it here.
The Explanation of the Pen Concerning
Allah's statement,
وَالْقَلَمِ
(By the pen) The apparent meaning is that this refers to the actual pen that is used to write. This is like Allah's saying,
(Read! And your Lord is the Most Generous. Who has taught by the pen. He has taught man that which he knew not.) (96:3-5) Therefore, this statement is Allah's swearing and alerting His creatures to what He has favored them with by teaching them the skill of writing, through which knowledge is attained. Thus, Allah continues by saying,
The preceding Surah dealt with the existence of Allah, His Oneness, and His knowledge and power, and adduced, as a positive proof of these attributes, was the fact that Allah is the Creator of death and life, and of the entire universe through whose component parts there runs the beautiful order that pervades the cosmos. He has created man to serve a sublime object and to achieve a noble goal. But man in his ingratitude has always rejected the Divine Message and consequently has been incurring Divine scourge. This is mentioned, in Surah Al-Mulk, with particular reference to the pagans of Makkah. The present Surah deals with the truth of the Holy Prophet's ﷺ claim, and gives sound and solid proof of it. Thus it rebuts the criticisms and taunts of the pagans against the Holy Prophet ﷺ . Their first criticism was that he is [ God forbid!] insane whereas he was perfectly sane person, an embodiment of knowledge and a paragon of virtues. Another reason why they probably called him insane is that whenever an installment of revelation descended upon the Holy Prophet ﷺ ، a physical change came over him. For instance the colour of his face would change and become red, or he would sometimes snore or he would at other times appear to be in grief, or there were times when he would hang his head down. When any of these states was over, he would recite the revealed verses to the people. This matter was beyond the understanding and perception of the pagans. Therefore, they regarded this experience of receiving revelation as insanity. Or they called him insane presumably because he put forward to his people and to the whole world that there is no object worthy of worship except Allah. He put it to them that their self-carved idols cannot be gods because they are insensate and lacking knowledge; and they lack the ability to benefit or harm anyone. His voice of Truth sounded alone yet with this lone voice of Truth without any apparent means and support, he stood unwaveringly against the whole world. People without any insight or foresight did not think that it was possible for him to achieve his goal and they called it insanity. Some called him insane for the sake of calling him insane, without any reason. Having no excuse to refute the teachings of Allah's Messenger ﷺ ، all the pagans could do was to dub him insane. The initial verses of Surah Al-Qalam refute under emphatic oath their false charges.
‘By the pen, and all that they write’ refers to historical record. In historical records of human memoirs accumulated and preserved in the shape of history, the Quran is an exceptional book and the bearer of that book an exceptional personality. This quality of being exceptional cannot be explained unless the Quran is accepted as the book of God and Muhammad as His Prophet.
