Luqman 31:13

Wa-ith qala luqmanu libnihiwahuwa yaAAithuhu ya bunayya latushrik billahi inna ashshirka lathulmunAAatheem

And [mention, O Muḥammad], when Luqmān said to his son while he was instructing him, "O my son, do not associate [anything] with Allāh. Indeed, association [with Him] is great injustice."

(Remember) when Luqmān said to his son, while he was advising him, “My dear son, do not ascribe partners to Allah. Indeed, ascribing partners to Allah (shirk) is grave transgression.”
