Hizb 2 picks up Al-Baqara immediately after the cow narrative that closed Hizb 1, continuing a critique of communities that quote scripture selectively or claim its promises exclusively for themselves. The sura then turns to Abraham: his and Ishmael's raising of the foundations of the House at Mecca, a sequence of trials God sets him and which he completes, and his prayer that a righteous line and a messenger reciting God's signs should arise from his own descendants, a request later tradition reads as anticipating Muhammad's own prophethood.
Running through this material is a dispute over who may rightly claim Abraham's legacy. The sura answers it directly: Abraham was neither a Jew nor a Christian in the sectarian sense those later communities gave those names, but a man of upright submission to God before either community existed, a position the Quran uses to argue that its own message restores something older than the disputes dividing the People of the Book in Muhammad's own time.
The hizb closes at verse 141, just before Al-Baqara turns to the controversy over the direction of prayer, the qibla, which becomes the opening subject of Hizb 3. The transition is characteristic of how these Medinan chapters work: a theological argument about Abraham gives way, without pause, to a concrete communal dispute the young Muslim community was actually living through.
