This is a chapter of immense benefit and great import. Only those who recognize the two kinds of tawḥīd will truly profit from it: (1) declarative, knowledge-based, report-driven tawḥīd, and (2) volitional, intentional, practical tawḥīd. The first is pointed to by the surah: “Say: He is Allah, One,” while the second is pointed to by the surah: “Say: O you disbelievers.”

Likewise, the Almighty says, “Say: ‘We believe in Allah and in what has been sent down to us …’” (Qur’an 2:135), which pertains to the first, and He says, “Say: ‘O People of the Scripture! Come to a word that is equitable between us and you …’” (Qur’an 3:64), which pertains to the second.
