Luqman Ayah 13

وَإِذْ قَالَ لُقْمَـٰنُ لِٱبْنِهِۦ وَهُوَ يَعِظُهُۥ يَـٰبُنَىَّ لَا تُشْرِكْ بِٱللَّهِ‌ۖ إِنَّ ٱلشِّرْكَ لَظُلْمٌ عَظِيمٌ ١٣ And ?remember? when Luqmân said to his son, while advising him, “O my dear son! Never associate ?anything? with Allah ?in worship?, for associating ?others with Him? is truly the worst of all wrongs.”
