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