The responsibility of parents in maintaining Islamic monotheism

فَلَمَّآ ءَاتَىٰهُمَا صَـٰلِحًا جَعَلَا لَهُۥ شُرَكَآءَ فِيمَآ ءَاتَىٰهُمَا ۚ فَتَعَـٰلَى ٱللَّهُ عَمَّا يُشْرِكُونَ

But when He gives them a good [child], they ascribe partners to Him concerning that which He has given them. Exalted is Allāh above what they associate with Him.
