This is Tafseer Ibn Kathir for Surah Al-Ahzab. This is NOT Abridged. This is book has about 95 pages just for this Surah alone from Tafseer Ibn Kathir. Before Allah discusses ideas and theoretical matters, He gives tangible examples: one man cannot have two hearts in his body, and a man's wife does not become his mother if he says the words of Zihar to her: "You are to me like the back of my mother.'' By the same token, an adopted child does not become the son of the man who adopts him and calls him his son.
