Sura al-Aʿrāf 7:203

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

wa-idhā lam taʾtihim bi-āyatin qālū lawlā ijtabaytahā qul innamā attabiʿu mā yūḥā ilayya min rrabbī hādhā baṣāʾiru min rabbikum wa-hudan wa-raḥmatun li-qawmin yuʾminūna

If thou bring them not a revelation, they say: "Why hast thou not got it together?" Say: "I but follow what is revealed to me from my Lord: this is (nothing but) lights from your Lord, and Guidance, and mercy, for any who have faith."
