But when He gives them a good [child], they1 ascribe partners to Him concerning that which He has given them. Exalted is Allāh above what they associate with Him.
Translation: Saheeh International (English)
1 The ungrateful man and woman or the polytheistic man and woman.
But when Allah responds to their prayer, and gives them a healthy child as they asked, they ascribe partners to Allah in what He gave to them when Allah is far above having any partner, and is alone in His divinity.
