7:203
وَإِذَا لَمۡ تَأۡتِهِم بِـَٔایَةࣲ قَالُوا۟ لَوۡلَا ٱجۡتَبَیۡتَهَاۚ قُلۡ إِنَّمَاۤ أَتَّبِعُ مَا یُوحَىٰۤ إِلَیَّ مِن رَّبِّیۚ هَـٰذَا بَصَاۤىِٕرُ مِن رَّبِّكُمۡ وَهُدࣰى وَرَحۡمَةࣱ لِّقَوۡمࣲ یُؤۡمِنُونَ
And when thou bringest not a verse for them they say: Why hast thou not chosen it? Say: I follow only that which is inspired in me from my Lord. This (Qur'an) is insight from your Lord, and a guidance and a mercy for a people that believe.
