Verse 203

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

And if you do not produce a sign for them, they say why not demand one. Say; indeed I obey what is inspired to me from my Lord. This is a portent from your Lord and guidance as well as a mercy for the people who have faith.
