﴿ وَإِذَا لَمْ تَأْتِهِم بِـَٔايَةٍۢ قَالُوا۟ لَوْلَا ٱجْتَبَيْتَهَا ۚ قُلْ إِنَّمَآ أَتَّبِعُ مَا يُوحَىٰٓ إِلَىَّ مِن رَّبِّى ۚ هَٰذَا بَصَآئِرُ مِن رَّبِّكُمْ وَهُدًۭى وَرَحْمَةٌۭ لِّقَوْمٍۢ يُؤْمِنُونَ ﴾

“And yet, when thou [O Prophet] dost not produce any miracle for them, some [people] say, "Why dost thou not seek to obtain it [from God]? Say: "I only follow whatever is being revealed to me by my Sustainer: this [revelation] is a means of insight from your Sustainer, and a guidance and grace unto people who will believe.”

And when you do not bring them that is the people of Mecca a sign from among those which they request they say ‘Why have you not chosen one?’ why have you not produced one all by yourself? Say to them ‘I follow only that which is revealed to me from my Lord and it is not for me to bring anything from myself; this Qur’ān is insight proofs from your Lord and a guidance and a mercy for a people who believe’.
