ترجمة الآية 203 من سورة Al-A‘raf - English - سورة الأعراف : عدد الآيات 206 - - الصفحة 176 - الجزء 9.
And if you do not bring them a miracle [according to their (i.e. Quraish-pagans') proposal], they say: "Why have you not brought it?" Say: "I but follow what is revealed to me from my Lord. This (the Quran) is nothing but evidences from your Lord, and a guidance and a mercy for a people who believe."
And when you, [O Muhammad], do not bring them a sign, they say, "Why have you not contrived it?" Say, "I only follow what is revealed to me from my Lord. This [Qur'an] is enlightenment from your Lord and guidance and mercy for a people who believe."
(7:203) [O Prophet!] When you do not produce before them any miracle, they say: 'Why do you not choose for yourself a miracle?' *151 Say to them: 'I follow only what is revealed to me by my Lord. This is nothing but a means of insight into the truth, and guidance and mercy from your Lord to the people who believe. *152
*151). This question is a taunt rather than a simple query. What the utterance implies is that if the claim to prophethood is genuine, it should have been supported by some miracle. The next verse contains a fitting rejoinder to the taunt.
*152). The Prophet (peace be on him) is being made to tell his opponents in clear terms that he has no power to get whatever he wants. Being God's Messenger, he is required to follow the directives of the One Who has sent him and has granted him the Qur'an which has the light of guidance. The major characteristic of this Book is that those who seek guidance from it do indeed find the right way. The moral excellence visible in the lives of those people who accept the Qur'an is testimony to the fact that they have been blessed with God's mercy.
