وَإِذَا لَمْ تَأْتِهِم بِـَٔايَةٍ قَالُوا۟ لَوْلَا ٱجْتَبَيْتَهَا ۚ قُلْ إِنَّمَآ أَتَّبِعُ مَا يُوحَىٰٓ إِلَىَّ مِن رَّبِّى ۚ هَـٰذَا بَصَآئِرُ مِن رَّبِّكُمْ وَهُدًى وَرَحْمَةٌ لِّقَوْمٍ يُؤْمِنُونَ

When you do not bring them a fresh revelation, they say, ‘But can you not just ask for one?’ Say, ‘I merely repeat what is revealed to me from my Lord: this revelation brings you insights from your Lord, and guidance and mercy for those who believe,
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 Qur’ân) is nothing but evidence from your Lord, and a guidance and a mercy for a people who believe."
