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 sign, they say, ‘Why do you not improvise one?’ Say, ‘I only follow what is revealed to me from my Lord; these are insights from your Lord, and a guidance and mercy for a people who have faith.’
