Following aayat

Holy Quran 18:110
قُلْ إِنَّمَا أَنَا بَشَرٌ مِّثْلُكُمْ يُوحَىٰ إِلَيَّ أَنَّمَا إِلَٰهُكُمْ إِلَٰهٌ وَاحِدٌ ۖ فَمَن كَانَ يَرْجُو لِقَاءَ رَبِّهِ فَلْيَعْمَلْ عَمَلًا صَالِحًا وَلَا يُشْرِكْ بِعِبَادَةِ رَبِّهِ أَحَدًا

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."
