Luqman (Luqman)

Surah 31 · Verse 13

and when Luqman said to his son while admonishing him, “O my son! do not associate (any partner) with Allah. Polytheism is certainly a great injustice.”

وَإِذْ قَالَ لُقْمَانُ لِابْنِهِ وَهُوَ يَعِظُهُ يَا بُنَيَّ لَا تُشْرِكْ بِاللَّهِ ۖ إِنَّ الشِّرْكَ لَظُلْمٌ عَظِيمٌ
