What the Disbelievers said about the Messenger , refutation of Their Words, and Their ultimate Destiny
Allah tells us about the disbelievers' stubborn resistance to and rejection of the truth, with no proof or evidence for doing so. Their excuse was, as they said:
مَا لِهَـذَا الرَّسُولِ يَأْكُلُ الطَّعَامَ
(Why does this Messenger eat food,) meaning, `as we eat, and why does he need food as we need it'
وَيَمْشِى فِى الاٌّسْوَاقِ
(and walk about in the markets.) means, he walks around and goes there often seeking to trade and earn a living.
(Why is not an angel sent down to him to be a warner with him) They were saying: why doesn't an angel come down to him from Allah, to be a witness that what he is claiming is true This is like when Fira`wn said:
The Second Objection was that if the Holy Prophet ﷺ was a prophet, he should not have been eating and drinking like common people; instead he should have been free from eating and drinking like angels. And if this was not so, he should have at least enough wealth and gardens to take care of his day to day needs, so that he may not need to care for his living. Furthermore, how could he be accepted as a prophet when he is neither an angel nor does an angel accompany him to endorse what he preaches, therefore it appears that he has been charmed by someone which has turned his head and that is why he talks like this. A general answer to this objection is given in the verse انظُرْ كَيْفَ ضَرَبُوا لَكَ لِلْعَالَمِينَ at is (See how they coined similes for you, so they have gone astray and cannot find a way. - 25:9). The detailed answer to the objection is given in the next few verses.
Tazkirul Quran
Maulana Wahiduddin KhanOn ayahs 9–15
Every preacher giving the call for Truth has had to face the same experience, as that of a Prophet. While his contemporaries looked down upon him with contempt, the people of succeeding ages venerated the preacher like a god. This is so because during his lifetime, a prophet lives the life of an ordinary human being and his contemporaries therefore fail to appreciate the wisdom he propagates. They see him cast in an overly idealized form, wearing the halo conferred by legend, and therefore, feel obliged to pay homage to him and glorify him in an exaggerated manner. The minds of succeeding generations develop such deep-seated notions about the extraordinary greatness of the prophet, that nobody is held superior to or even at par with him. A living prophet, however, is treated scornfully by the majority of his contemporaries. The few who develop a reasoned understanding of his message are also ‘advised’ to disassociate themselves from one who is “possessed”. Having no rational arguments, the unrelenting contemporaries of a prophet, resort to unfair vilification of his image so as to curb the preaching of his message.
