Mada kuu ya msingi ya sura hii ni umoja wa Mungu, ikikataa dhana zote na mawazo yanayompa Mungu mwana au mshirika. Pia inagusa suala muhimu la ufufuo, ambalo limefungamana kwa karibu na dhana ya umoja wa Mungu. Katika hili, sura hii inafuata mtindo uleule wa sura nyingi, kama sio zote, zilizoteremshwa Makka.

The central theme of this sūrah focuses on God’s oneness, rejecting all concepts and ideas assigning a son or a partner to Him. It also touches on the important issue of resurrection, intertwined as it is with the concept of God’s oneness. In this, the sūrah follows the same pattern as most, if not all, sūrahs revealed in Makkah.

Sura hii inachunguza mada yake kupitia hadithi kadhaa, zikianza na hadithi ya Zakaria na mwanawe, Yahya, kisha inafuata hadithi ya Maryamu na kuzaliwa kwa Isa. Baadaye kuna sehemu ya hadithi ya Ibrahimu pamoja na baba yake, ikifuatiwa na marejeo mafupi ya manabii wengine: Isaka, Yakobo, Musa, Harun, Ismaili, Idrisi, Adamu na Nuhu. Hadithi hizi zinachukua karibu theluthi mbili ya sura, zikisisitiza ukweli wa umoja wa Mungu, ufufuo, na kutokuwepo kwa watoto au washirika wowote kwa Mungu.
