Al-Kahf 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 man like you, to whom has been revealed that your god is one God. So whoever would hope for the meeting with his Lord - let him do righteous work and not associate in the worship of his Lord anyone.""
Al-Kahf 18:110, translation by Sahih International
A short reflection
Whoever hopes for the meeting with his Lord, let him do righteous work, and not associate anyone in the worship of his Lord.
