(And (remember) when Luqman said unto his son) Salam, (when he was exhorting him) when he was enjoining him to do good and forbidding him to engage in evil: (O my dear son! Ascribe no partners unto Allah. Lo! to ascribe partners (unto Him) is a tremendous wrong) it is a great sin which is punished by Allah.
- 31:1313
وَإِذْ قَالَ لُقْمَانُ لِابْنِهِ وَهُوَ يَعِظُهُ يَا بُنَيَّ لَا تُشْرِكْ بِاللَّهِ ۖ إِنَّ الشِّرْكَ لَظُلْمٌ عَظِيمٌ
And recall what time Luqman said unto his son, while he was exhorting him: O my son! associate not aught with Allah; verily this associating is surely a tremendous wrong.
