يَعْرِفُونَهُ كَمَا يَعْرِفُونَ أَبْنَاءَهُمْ
They recognize him as they recognize their own sons. (Qur'an 2:146)
The example requires recognition to be distinguished from religious acceptance. Recognition is attributed to some among the People of the Book, yet their refusal to accept the truth is also discussed.
Recognition: understanding a report, sign, or person.
Faithful assent: accepting the truth recognized and submitting to it inwardly.
The distinction explains why the technical theological definition of faith is not reduced to mere knowledge or identification.
