Those to whom We have given the Scripture (Jews and Christians) recognize him (i.e. Muhammad SAW as a Messenger of Allah, and they also know that there is no Ilah (God) but Allah and Islam is Allah's Religion), as they recognize their own sons. Those who destroy themselves will not believe. (Tafsir At-Tabari)
کسانی که کتاب (وحیانی) به آنان داده‌ایم، همان‌گونه که پسران خود را می‌شناسند او [:پیامبر و کتابش] را (هم) می‌شناسند. پس کسانی که خودشان را (باخته و) زیان کرده‌اند، (هم)آنان ایمان نمی‌آورند.
