Qur'an 18:110

قُلْ إِنَّمَآ أَنَا۠ بَشَرٌ مِّثْلُكُمْ يُوحَىٰٓ إِلَىَّ أَنَّمَآ إِلَـٰهُكُمْ إِلَـٰهٌ وَٰحِدٌ ۖ فَمَن كَانَ يَرْجُوا۟ لِقَآءَ رَبِّهِۦ فَلْيَعْمَلْ عَمَلًا صَـٰلِحًا وَلَا يُشْرِكْ بِعِبَادَةِ رَبِّهِۦٓ أَحَدًۢا

Say: I am only a mortal like you. My Lord inspireth in me that your Allah is only One Allah. And whoever hopeth for the meeting with his Lord, let him do righteous work, and make none sharer of the worship due unto his Lord.
