Incidentally...
Incidentally, his delay did not intrude upon his infallibility nor was it incompatible with it, for at that time, there was no urgency to convey Allah’s message. Thus, owing to considerations which were not personal but based upon expediency, he could postpone conveying the verses. With the revelation of this verse, those considerations were set aside and the message had now to be conveyed without delay.
The verse says: “So perhaps you may (be inclined) to give up a part of what is revealed unto thee, and your breast becomes straitened by it lest they say, ‘Why has not a treasure been sent down unto him or an angel not come with him?’...” Perhaps, the delay in conveying the revelations had been confined solely to a few obstinate people, of whose guidance the Prophet (S) had despaired.
However, Allah ordered that although they might not become believers, it was the duty of the Prophet (S) not to abandon them.
The verse continues saying: “…Verily you are only a warner, and Allah is custodian over everything.” Therefore, a leader and an authority in propagating the message of Islam must be always decisive in propagating and conveying the word of Allah, remaining undaunted by the people’s words and pretexts, for Allah is the guarantor of a prophet’s duty and prophets are not responsible for the consequences. They must act according to their duty and leave the rest to the Almighty.
Say, ‘Bring you then ten suras forged, like unto it, and call (to your aid) whomsoever you can, other than Allah, if you are truthful!’” The Qur’an is not only a miracle of eloquence in itself, it is also a miracle from the view point of its wisdom and ideology, its admonitions, its reasoning, the news it gives of the invisible world and its legislations.
The sentence, “and call to your aid whomsoever you can” is a call addressed to everyone, and not only to those Arabs who could comprehend the eloquence and the fluency of the noble Qur’an.
