The Holy Quran 31:13 — Surah Luqman
Arabic text
وَإِذْ قَالَ لُقْمَـٰنُ لِٱبْنِهِۦ وَهُوَ يَعِظُهُۥ يَـٰبُنَىَّ لَا تُشْرِكْ بِٱللَّهِ ۖ إِنَّ ٱلشِّرْكَ لَظُلْمٌ عَظِيمٌ
Translation
(The time deserves mention) When Luqmaan advised his son saying, "O my beloved son! Do not ascribe partners to Allaah. Without doubt, Shirk is the worst injustice (because it equates unworthy beings with Allaah)."
Tafsir (excerpt) — Tafsir Usmani
The counsel to his son not to associate partners with Allah: it is not known whether the son was an idolater and [Luqman] wanted to make him understand and bring him onto the right path, or whether he was a believer in tawhid (the Oneness of Allah) and [Luqman] gave this counsel in order to strengthen him firmly and keep him steadfast in tawhid.
